-@section DEC 21240 Driver Introduction
-
-@c XXX add back in cross reference to list of boards.
-
-One aim of our project is to port RTEMS on a standard PowerPC platform.
-To achieve it, we have chosen a Motorola MCP750 board. This board includes
-an Ethernet controller based on a DEC21140 chip. Because RTEMS has a
-TCP/IP stack, we will
-have to develop the DEC21140 related ethernet driver for the PowerPC port of
-RTEMS. As this controller is able to support 100Mbps network and as there is
-a lot of PCI card using this DEC chip, we have decided to first
-implement this driver on an Intel PC386 target to provide a solution for using
-RTEMS on PC with the 100Mbps network and then to port this code on PowerPC in
-a second phase.
-
-
-The aim of this document is to give some PCI board generalities and
-to explain the software architecture of the RTEMS driver. Finally, we will see
-what will be done for ChorusOs and Netboot environment .

-@section DEC21140 PCI Board Generalities
-
-@c XXX add crossreference to PCI Register Figure
-This chapter describes rapidely the PCI interface of this Ethernet controller.
-The board we have chosen for our PC386 implementation is a D-Link DFE-500TX.
-This is a dual-speed 10/100Mbps Ethernet PCI adapter with a DEC21140AF chip.
-Like other PCI devices, this board has a PCI device's header containing some
-required configuration registers, as shown in the PCI Register Figure.
-By reading
-or writing these registers, a driver can obtain information about the type of
-the board, the interrupt it uses, the mapping of the chip specific registers, ...
-
-
-
-On Intel target, the chip specific registers can be accessed via 2
-methods : I/O port access or PCI address mapped access. We have chosen to implement
-the PCI address access to obtain compatible source code to the port the driver
-on a PowerPC target.

-@c XXX add crossreference to PCI Register Figure
-
-On RTEMS, a PCI API exists. We have used it to configure the board. After initializing
-this PCI module via the @code{pci_initialize()} function, we try to detect
-the DEC21140 based ethernet board. This board is characterized by its Vendor
-ID (0x1011) and its Device ID (0x0009). We give these arguments to the
-@code{pcib_find_by_deviceid}
-function which returns , if the device is present, a pointer to the configuration
-header space (see PCI Registers Fgure). Once this operation performed,
-the driver
-is able to extract the information it needs to configure the board internal
-registers, like the interrupt line, the base address,... The board internal
-registers will not be detailled here. You can find them in @b{DIGITAL
-Semiconductor 21140A PCI Fast Ethernet LAN Controller
-- Hardware Reference Manual}.

-
-@section RTEMS Driver Software Architecture
-
-In this chapter will see the initialization phase, how the controller uses the
-host memory and the 2 threads launched at the initialization time.
-
-
-@subsection Initialization phase
-
-The DEC21140 Ethernet driver keeps the same software architecture than the other
-RTEMS ethernet drivers. The only API the programmer can use is the @code{rtems_dec21140_driver_attach}
-@code{(struct rtems_bsdnet_ifconfig *config)} function which
-detects the board and initializes the associated data structure (with registers
-base address, entry points to low-level initialization function,...), if the
-board is found.
-
-Once the attach function executed, the driver initializes the DEC
-chip. Then the driver connects an interrupt handler to the interrupt line driven
-by the Ethernet controller (the only interrupt which will be treated is the
-receive interrupt) and launches 2 threads : a receiver thread and a transmitter
-thread. Then the driver waits for incoming frame to give to the protocol stack
-or outcoming frame to send on the physical link.
-
-
-@subsection Memory Buffer
-
-@c XXX add cross reference to Problem
-This DEC chip uses the host memory to store the incoming Ethernet frames and
-the descriptor of these frames. We have chosen to use 7 receive buffers and
-1 transmit buffer to optimize memory allocation due to cache and paging problem
-that will be explained in the section @b{Encountered Problems}.
-
-
-To reference these buffers to the DEC chip we use a buffer descriptors
-ring. The descriptor structure is defined in the Buffer Descriptor Figure.
-Each descriptor
-can reference one or two memory buffers. We choose to use only one buffer of
-1520 bytes per descriptor.
-
-
-The difference between a receive and a transmit buffer descriptor
-is located in the status and control bits fields. We do not give details here,
-please refer to the [DEC21140 Hardware Manual].

-<IMG SRC="recvbd.jpg" ALT="Buffer Descriptor">
-@end html
-@end ifset
-
-
-
-@subsection Receiver Thread
-
-This thread is event driven. Each time a DEC PCI board interrupt occurs, the
-handler checks if this is a receive interrupt and send an event ``reception''
-to the receiver thread which looks into the entire buffer descriptors ring the
-ones that contain a valid incoming frame (bit OWN=0 means descriptor belongs
-to host processor). Each valid incoming ethernet frame is sent to the protocol
-stack and the buffer descriptor is given back to the DEC board (the host processor
-reset bit OWN, which means descriptor belongs to 21140).
-
-
-@subsection Transmitter Thread
-
-This thread is also event driven. Each time an Ethernet frame is put in the
-transmit queue, an event is sent to the transmit thread, which empty the queue
-by sending each outcoming frame. Because we use only one transmit buffer, we
-are sure that the frame is well-sent before sending the next.
-
-
-@section Encountered Problems
-
-On Intel PC386 target, we were faced with a problem of memory cache management.
-Because the DEC chip uses the host memory to store the incoming frame and because
-the DEC21140 configuration registers are mapped into the PCI address space,
-we must ensure that the data read (or written) by the host processor are the
-ones written (or read) by the DEC21140 device in the host memory and not old
-data stored in the cache memory. Therefore, we had to provide a way to manage
-the cache. This module is described in the document @b{RTEMS
-Cache Management For Intel}. On Intel, the
-memory region cache management is available only if the paging unit is enabled.
-We have used this paging mechanism, with 4Kb page. All the buffers allocated
-to store the incoming or outcoming frames, buffer descriptor and also the PCI
-address space of the DEC board are located in a memory space with cache disable.
-
-
-Concerning the buffers and their descriptors, we have tried to optimize
-the memory space in term of allocated page. One buffer has 1520 bytes, one descriptor
-has 16 bytes. We have 7 receive buffers and 1 transmit buffer, and for each,
-1 descriptor : (7+1)*(1520+16) = 12288 bytes = 12Kb = 3 entire pages. This
-allows not to lose too much memory or not to disable cache memory for a page
-which contains other data than buffer, which could decrease performance.
-
-
-@section ChorusOs DEC Driver
-
-Because ChorusOs is used in several Canon CRF projects, we must provide such
-a driver on this OS to ensure compatibility between the RTEMS and ChorusOs developments.
-On ChorusOs, a DEC driver source code already exists but only for a PowerPC
-target. We plan to port this code (which uses ChorusOs API) on Intel target.
-This will allow us to have homogeneous developments. Moreover, the port of the
-development performed with ChorusOs environment to RTEMS environment will be
-easier for the developers.
-
-
-@section Netboot DEC driver
-
-We use Netboot tool to load our development from a server to the target via
-an ethernet network. Currently, this tool does not support the DEC board. We
-plan to port the DEC driver for the Netboot tool.
-
-
-But concerning the port of the DEC driver into Netboot, we are faced
-with a problem : in RTEMS environment, the DEC driver is interrupt or event
-driven, in Netboot environment, it must be used in polling mode. It means that
-we will have to re-write some mechanisms of this driver.
-
-
-@section List of Ethernet cards using the DEC chip
-
-Many Ethernet adapter cards use the Tulip chip. Here is a non exhaustive list
-of adapters which support this driver :
-
-@itemize @bullet
-@item Accton EtherDuo PCI.
-@item Accton EN1207 All three media types supported.
-@item Adaptec ANA6911/TX 21140-AC.

-@chapter Networking Driver
-
-@section Introduction
-
-This chapter is intended to provide an introduction to the
-procedure for writing RTEMS network device drivers.
-The example code is taken from the `Generic 68360' network device
-driver. The source code for this driver is located in the
-@code{c/src/lib/libbsp/m68k/gen68360/network} directory in the RTEMS
-source code distribution. Having a copy of this driver at
-hand when reading the following notes will help significantly.
-
-@section Learn about the network device
-
-Before starting to write the network driver become completely
-familiar with the programmer's view of the device.
-The following points list some of the details of the
-device that must be understood before a driver can be written.
-
-@itemize @bullet
-
-@item Does the device use DMA to transfer packets to and from
-memory or does the processor have to
-copy packets to and from memory on the device?
-
-@item If the device uses DMA, is it capable of forming a single
-outgoing packet from multiple fragments scattered in separate
-memory buffers?
-
-@item If the device uses DMA, is it capable of chaining multiple
-outgoing packets, or does each outgoing packet require
-intervention by the driver?
-
-@item Does the device automatically pad short frames to the minimum
-64 bytes or does the driver have to supply the padding?
-
-@item Does the device automatically retry a transmission on detection
-of a collision?
-
-@item If the device uses DMA, is it capable of buffering multiple
-packets to memory, or does the receiver have to be restarted
-after the arrival of each packet?
-
-@item How are packets that are too short, too long, or received with
-CRC errors handled? Does the device automatically continue
-reception or does the driver have to intervene?
-
-@item How is the device Ethernet address set? How is the device
-programmed to accept or reject broadcast and multicast packets?
-
-@item What interrupts does the device generate? Does it generate an
-interrupt for each incoming packet, or only for packets received
-without error? Does it generate an interrupt for each packet
-transmitted, or only when the transmit queue is empty? What
-happens when a transmit error is detected?
-
-@end itemize
-
-In addition, some controllers have specific questions regarding
-board specific configuration. For example, the SONIC Ethernet
-controller has a very configurable data bus interface. It can
-even be configured for sixteen and thirty-two bit data buses. This
-type of information should be obtained from the board vendor.
-
-@section Understand the network scheduling conventions
-
-When writing code for the driver transmit and receive tasks,
-take care to follow the network scheduling conventions. All tasks
-which are associated with networking share various
-data structures and resources. To ensure the consistency
-of these structures the tasks
-execute only when they hold the network semaphore (@code{rtems_bsdnet_semaphore}).
-The transmit and receive tasks must abide by this protocol. Be very
-careful to avoid `deadly embraces' with the other network tasks.
-A number of routines are provided to make it easier for the network
-driver code to conform to the network task scheduling conventions.
-
-@itemize @bullet
-
-@item @code{void rtems_bsdnet_semaphore_release(void)}
-
-This function releases the network semaphore.
-The network driver tasks must call this function immediately before
-making any blocking RTEMS request.
-
-@item @code{void rtems_bsdnet_semaphore_obtain(void)}
-
-This function obtains the network semaphore.
-If a network driver task has released the network semaphore to allow other
-network-related tasks to run while the task blocks, then this function must
-be called to reobtain the semaphore immediately after the return from the
-blocking RTEMS request.
-
-@item @code{rtems_bsdnet_event_receive(rtems_event_set, rtems_option, rtems_interval, rtems_event_set *)}
-The network driver task should call this function when it wishes to wait
-for an event. This function releases the network semaphore,
-calls @code{rtems_event_receive} to wait for the specified event
-or events and reobtains the semaphore.
-The value returned is the value returned by the @code{rtems_event_receive}.
-
-@end itemize
-
-@section Network Driver Makefile
-
-Network drivers are considered part of the BSD network package and as such
-are to be compiled with the appropriate flags. This can be accomplished by
-adding @code{-D__INSIDE_RTEMS_BSD_TCPIP_STACK__} to the @code{command line}.
-If the driver is inside the RTEMS source tree or is built using the
-RTEMS application Makefiles, then adding the following line accomplishes
-this:
-
-@example
-DEFINES += -D__INSIDE_RTEMS_BSD_TCPIP_STACK__
-@end example
-
-This is equivalent to the following list of definitions. Early versions
-of the RTEMS BSD network stack required that all of these be defined.
-
-@example
--D_COMPILING_BSD_KERNEL_ -DKERNEL -DINET -DNFS \
- -DDIAGNOSTIC -DBOOTP_COMPAT
-@end example
-
-Defining these macros tells the network header files that the driver
-is to be compiled with extended visibility into the network stack. This
-is in sharp contrast to applications that simply use the network stack.
-Applications do not require this level of visibility and should stick
-to the portable application level API.
-
-As a direct result of being logically internal to the network stack,
-network drivers use the BSD memory allocation routines This means,
-for example, that malloc takes three arguments. See the SONIC
-device driver (@code{c/src/lib/libchip/network/sonic.c}) for an example
-of this. Because of this, network drivers should not include
-@code{<stdlib.h>}. Doing so will result in conflicting definitions
-of @code{malloc()}.
-
-@b{Application level} code including network servers such as the FTP
-daemon are @b{not} part of the BSD kernel network code and should not be
-compiled with the BSD network flags. They should include
-@code{<stdlib.h>} and not define the network stack visibility
-macros.
-
-@section Write the Driver Attach Function
-
-The driver attach function is responsible for configuring the driver
-and making the connection between the network stack
-and the driver.
-
-Driver attach functions take a pointer to an
-@code{rtems_bsdnet_ifconfig} structure as their only argument.
-and set the driver parameters based on the
-values in this structure. If an entry in the configuration
-structure is zero the attach function chooses an
-appropriate default value for that parameter.
-
-
-The driver should then set up several fields in the ifnet structure
-in the device-dependent data structure supplied and maintained by the driver:
-
-@table @code
-@item ifp->if_softc
-Pointer to the device-dependent data. The first entry
-in the device-dependent data structure must be an @code{arpcom}
-structure.
-
-@item ifp->if_name
-The name of the device. The network stack uses this string
-and the device number for device name lookups. The device name should
-be obtained from the @code{name} entry in the configuration structure.
-
-@item ifp->if_unit
-The device number. The network stack uses this number and the
-device name for device name lookups. For example, if
-@code{ifp->if_name} is @samp{scc} and @code{ifp->if_unit} is @samp{1},
-the full device name would be @samp{scc1}. The unit number should be
-obtained from the `name' entry in the configuration structure.
-
-@item ifp->if_mtu
-The maximum transmission unit for the device. For Ethernet
-devices this value should almost always be 1500.
-
-@item ifp->if_flags
-The device flags. Ethernet devices should set the flags
-to @code{IFF_BROADCAST|IFF_SIMPLEX}, indicating that the
-device can broadcast packets to multiple destinations
-and does not receive and transmit at the same time.
-
-@item ifp->if_snd.ifq_maxlen
-The maximum length of the queue of packets waiting to be
-sent to the driver. This is normally set to @code{ifqmaxlen}.
-
-@item ifp->if_init
-The address of the driver initialization function.
-
-@item ifp->if_start
-The address of the driver start function.
-
-@item ifp->if_ioctl
-The address of the driver ioctl function.
-
-@item ifp->if_output
-The address of the output function. Ethernet devices
-should set this to @code{ether_output}.
-@end table
-
-RTEMS provides a function to parse the driver name in the
-configuration structure into a device name and unit number.
-
-@example
-int rtems_bsdnet_parse_driver_name (
- const struct rtems_bsdnet_ifconfig *config,
- char **namep
-);
-@end example
-
-The function takes two arguments; a pointer to the configuration
-structure and a pointer to a pointer to a character. The function
-parses the configuration name entry, allocates memory for the driver
-name, places the driver name in this memory, sets the second argument
-to point to the name and returns the unit number.
-On error, a message is printed and -1 is returned.
-
-Once the attach function has set up the above entries it must link the
-driver data structure onto the list of devices by
-calling @code{if_attach}. Ethernet devices should then
-call @code{ether_ifattach}. Both functions take a pointer to the
-device's @code{ifnet} structure as their only argument.
-
-The attach function should return a non-zero value to indicate that
-the driver has been successfully configured and attached.
-
-@section Write the Driver Start Function.
-This function is called each time the network stack wants to start the
-transmitter. This occures whenever the network stack adds a packet
-to a device's send queue and the @code{IFF_OACTIVE} bit in the
-device's @code{if_flags} is not set.
-
-For many devices this function need only set the @code{IFF_OACTIVE} bit in the
-@code{if_flags} and send an event to the transmit task
-indicating that a packet is in the driver transmit queue.
-
-
-@section Write the Driver Initialization Function.
-
-This function should initialize the device, attach to interrupt handler,
-and start the driver transmit and receive tasks. The function
-
-@example
-rtems_id
-rtems_bsdnet_newproc (char *name,
- int stacksize,
- void(*entry)(void *),
- void *arg);
-@end example
-
-should be used to start the driver tasks.
-
-Note that the network stack may call the driver initialization function more
-than once.
-Make sure multiple versions of the receive and transmit tasks are not accidentally
-started.
-
-
-
-@section Write the Driver Transmit Task
-
-This task is reponsible for removing packets from the driver send queue and sending them to the device. The task should block waiting for an event from the
-driver start function indicating that packets are waiting to be transmitted.
-When the transmit task has drained the driver send queue the task should clear
-the @code{IFF_OACTIVE} bit in @code{if_flags} and block until another outgoing
-packet is queued.
-
-
-@section Write the Driver Receive Task
-This task should block until a packet arrives from the device. If the
-device is an Ethernet interface the function @code{ether_input} should be called
-to forward the packet to the network stack. The arguments to @code{ether_input}
-are a pointer to the interface data structure, a pointer to the ethernet
-header and a pointer to an mbuf containing the packet itself.
-
-
-
-
-@section Write the Driver Interrupt Handler
-A typical interrupt handler will do nothing more than the hardware
-manipulation required to acknowledge the interrupt and send an RTEMS event
-to wake up the driver receive or transmit task waiting for the event.
-Network interface interrupt handlers must not make any calls to other
-network routines.
-
-
-
-@section Write the Driver IOCTL Function
-This function handles ioctl requests directed at the device. The ioctl
-commands which must be handled are:
-
-@table @code
-@item SIOCGIFADDR
-@item SIOCSIFADDR
-If the device is an Ethernet interface these
-commands should be passed on to @code{ether_ioctl}.
-
-@item SIOCSIFFLAGS
-This command should be used to start or stop the device,
-depending on the state of the interface @code{IFF_UP} and
-@code{IFF_RUNNING} bits in @code{if_flags}:
-@table @code
-@item IFF_RUNNING
-Stop the device.
-
-@item IFF_UP
-Start the device.
-
-@item IFF_UP|IFF_RUNNING
-Stop then start the device.
-
-@item 0
-Do nothing.
-
-@end table
-@end table
-
-
-
-@section Write the Driver Statistic-Printing Function
-This function should print the values of any statistic/diagnostic
-counters the network driver may use. The driver ioctl function should call
-the statistic-printing function when the ioctl command is
-@code{SIO_RTEMS_SHOW_STATS}.

-@chapter Using Networking in an RTEMS Application
-
-@section Makefile changes
-@subsection Including the required managers
-The FreeBSD networking code requires several RTEMS managers
-in the application:
-
-@example
-MANAGERS = io event semaphore
-@end example
-
-@subsection Increasing the size of the heap
-The networking tasks allocate a lot of memory. For most applications
-the heap should be at least 256 kbytes.
-The amount of memory set aside for the heap can be adjusted by setting
-the @code{CFLAGS_LD} definition as shown below:
-
-@example
-CFLAGS_LD += -Wl,--defsym -Wl,HeapSize=0x80000
-@end example
-
-This sets aside 512 kbytes of memory for the heap.
-
-@section System Configuration
-
-The networking tasks allocate some RTEMS objects. These
-must be accounted for in the application configuration table. The following
-lists the requirements.
-
-@table @b
-@item TASKS
-One network task plus a receive and transmit task for each device.
-
-@item SEMAPHORES
-One network semaphore plus one syslog mutex semaphore if the application uses
-openlog/syslog.
-
-@item EVENTS
-The network stack uses @code{RTEMS_EVENT_24} and @code{RTEMS_EVENT_25}.
-This has no effect on the application configuration, but
-application tasks which call the network functions should not
-use these events for other purposes.
-
-@end table
-
-@section Initialization
-@subsection Additional include files
-The source file which declares the network configuration
-structures and calls the network initialization function must include
-
-@example
-#include <rtems/rtems_bsdnet.h>
-@end example
-
-@subsection Network Configuration
-The network configuration is specified by declaring
-and initializing the @code{rtems_bsdnet_config}
-structure.
-
-@example
-@group
-struct rtems_bsdnet_config @{
- /*
- * This entry points to the head of the ifconfig chain.
- */
- struct rtems_bsdnet_ifconfig *ifconfig;
-
- /*
- * This entry should be rtems_bsdnet_do_bootp if BOOTP

-
-The structure entries are described in the following table.
-If your application uses BOOTP/DHCP to obtain network configuration
-information and if you are happy with the default values described
-below, you need to provide only the first two entries in this structure.
-
-@table @code
-
-@item struct rtems_bsdnet_ifconfig *ifconfig
-A pointer to the first configuration structure of the first network
-device. This structure is described in the following section.
-You must provide a value for this entry since there is no default value for it.
-
-@item void (*bootp)(void)
-This entry should be set to @code{rtems_bsdnet_do_bootp} if your
-application by default uses the BOOTP/DHCP client protocol to obtain
-network configuration information. It should be set to @code{NULL} if
-your application does not use BOOTP/DHCP.
-
-You can also use @code{rtems_bsdnet_do_bootp_rootfs} to have a set of
-standard files created with the information return by the BOOTP/DHCP
-protocol. The IP address is added to @file{/etc/hosts} with the host
-name and domain returned. If no host name or domain is returned
-@code{me.mydomain} is used. The BOOTP/DHCP server's address is also
-added to @file{/etc/hosts}. The domain name server listed in the
-BOOTP/DHCP information are added to @file{/etc/resolv.conf}. A
-@code{search} record is also added if a domain is returned. The files
-are created if they do not exist.
-
-The default @code{rtems_bsdnet_do_bootp} and
-@code{rtems_bsdnet_do_bootp_rootfs} handlers will loop for-ever
-waiting for a BOOTP/DHCP server to respond. If an error is detected
-such as not valid interface or valid hardware address the target will
-reboot allowing any hardware reset to correct itself.
-
-You can provide your own custom handler which allows you to perform
-an initialization that meets your specific system requirements. For
-example you could try BOOTP/DHCP then enter a configuration tool if no
-server is found allowing the user to switch to a static configuration.
-
-@item int network_task_priority
-The priority at which the network task and network device
-receive and transmit tasks will run.
-If a value of 0 is specified the tasks will run at priority 100.
-
-@item unsigned long mbuf_bytecount
-The number of bytes to allocate from the heap for use as mbufs.
-If a value of 0 is specified, 64 kbytes will be allocated.
-
-@item unsigned long mbuf_cluster_bytecount
-The number of bytes to allocate from the heap for use as mbuf clusters.
-If a value of 0 is specified, 128 kbytes will be allocated.
-
-@item char *hostname
-The host name of the system.
-If this, or any of the following, entries are @code{NULL} the value
-may be obtained from a BOOTP/DHCP server.
-
-@item char *domainname
-The name of the Internet domain to which the system belongs.
-
-@item char *gateway
-The Internet host number of the network gateway machine,
-specified in 'dotted decimal' (@code{129.128.4.1}) form.
-
-@item char *log_host
-The Internet host number of the machine to which @code{syslog} messages
-will be sent.
-
-@item char *name_server[3]
-The Internet host numbers of up to three machines to be used as
-Internet Domain Name Servers.
-
-@item char *ntp_server[3]
-The Internet host numbers of up to three machines to be used as
-Network Time Protocol (NTP) Servers.
-
-@item unsigned long sb_efficiency
-This is the first of five configuration parameters related to
-the amount of memory each socket may consume for buffers. The
-TCP/IP stack reserves buffers (e.g. mbufs) for each open socket. The
-TCP/IP stack has different limits for the transmit and receive
-buffers associated with each TCP and UDP socket. By tuning these
-parameters, the application developer can make trade-offs between
-memory consumption and performance. The default parameters favor
-performance over memory consumption. See
-@uref{http://www.rtems.org/ml/rtems-users/2004/february/msg00200.html}
-for more details but note that after the RTEMS 4.8 release series,
-the sb_efficiency default was changed from @code{8} to @code{2}.
-
-The user should also be aware of the @code{SO_SNDBUF} and @code{SO_RCVBUF}
-IO control operations. These can be used to specify the
-send and receive buffer sizes for a specific socket. There
-is no standard IO control to change the @code{sb_efficiency} factor.
-
-The @code{sb_efficiency} parameter is a buffering factor used
-in the implementation of the TCP/IP stack. The default is @code{2}
-which indicates double buffering. When allocating memory for each
-socket, this number is multiplied by the buffer sizes for that socket.
-
-@item unsigned long udp_tx_buf_size
-This configuration parameter specifies the maximum amount of
-buffer memory which may be used for UDP sockets to transmit
-with. The default size is 9216 bytes which corresponds to
-the maximum datagram size.
-
-@item unsigned long udp_rx_buf_size
-This configuration parameter specifies the maximum amount of
-buffer memory which may be used for UDP sockets to receive
-into. The default size is the following length in bytes:
-
-@example
-40 * (1024 + sizeof(struct sockaddr_in)
-@end example
-
-@item unsigned long tcp_tx_buf_size
-This configuration parameter specifies the maximum amount of
-buffer memory which may be used for TCP sockets to transmit
-with. The default size is sixteen kilobytes.
-
-@item unsigned long tcp_rx_buf_size
-This configuration parameter specifies the maximum amount of
-buffer memory which may be used for TCP sockets to receive
-into. The default size is sixteen kilobytes.
-
-@item const cpu_set_t *network_task_cpuset
-This configuration parameter specifies the CPU affinity of the
-network task. If set to @code{0} the network task can be scheduled on
-any CPU. Only available in SMP configurations.
-
-@item size_t network_task_cpuset_size
-This configuration parameter specifies the size of the
-@code{network_task_cpuset} used. Only available in SMP configurations.
-
-@end table
-
-In addition, the following fields in the @code{rtems_bsdnet_ifconfig}
-are of interest.
-
-@table @b
-
-@item int port
-The I/O port number (ex: 0x240) on which the external Ethernet
-can be accessed.
-
-@item int irno
-The interrupt number of the external Ethernet controller.
-
-@item int bpar
-The address of the shared memory on the external Ethernet controller.
-
-
-@end table
-
-@subsection Network device configuration
-Network devices are specified and configured by declaring and initializing a
-@code{struct rtems_bsdnet_ifconfig} structure for each network device.
-
-The structure entries are described in the following table. An application
-which uses a single network interface, gets network configuration information
-from a BOOTP/DHCP server, and uses the default values for all driver
-parameters needs to initialize only the first two entries in the
-structure.
-
-@table @code
-@item char *name
-The full name of the network device. This name consists of the
-driver name and the unit number (e.g. @code{"scc1"}).
-The @code{bsp.h} include file usually defines RTEMS_BSP_NETWORK_DRIVER_NAME as
-the name of the primary (or only) network driver.
-
-@item int (*attach)(struct rtems_bsdnet_ifconfig *conf)
-The address of the driver @code{attach} function. The network
-initialization function calls this function to configure the driver and
-attach it to the network stack.
-The @code{bsp.h} include file usually defines RTEMS_BSP_NETWORK_DRIVER_ATTACH as
-the name of the attach function of the primary (or only) network driver.
-
-@item struct rtems_bsdnet_ifconfig *next
-A pointer to the network device configuration structure for the next network
-interface, or @code{NULL} if this is the configuration structure of the
-last network interface.
-
-@item char *ip_address
-The Internet address of the device,
-specified in `dotted decimal' (@code{129.128.4.2}) form, or @code{NULL}
-if the device configuration information is being obtained from a
-BOOTP/DHCP server.
-
-@item char *ip_netmask
-The Internet inetwork mask of the device,
-specified in `dotted decimal' (@code{255.255.255.0}) form, or @code{NULL}
-if the device configuration information is being obtained from a
-BOOTP/DHCP server.
-
-
-@item void *hardware_address
-The hardware address of the device, or @code{NULL} if the driver is
-to obtain the hardware address in some other way (usually by reading
-it from the device or from the bootstrap ROM).
-
-@item int ignore_broadcast
-Zero if the device is to accept broadcast packets, non-zero if the device
-is to ignore broadcast packets.
-
-@item int mtu
-The maximum transmission unit of the device, or zero if the driver
-is to choose a default value (typically 1500 for Ethernet devices).
-
-@item int rbuf_count
-The number of receive buffers to use, or zero if the driver is to
-choose a default value
-
-@item int xbuf_count
-The number of transmit buffers to use, or zero if the driver is to
-choose a default value
-Keep in mind that some network devices may use 4 or more
-transmit descriptors for a single transmit buffer.
-
-@end table
-
-A complete network configuration specification can be as simple as the one
-shown in the following example.
-This configuration uses a single network interface, gets
-network configuration information
-from a BOOTP/DHCP server, and uses the default values for all driver
-parameters.
-
-@example
-static struct rtems_bsdnet_ifconfig netdriver_config = @{
- RTEMS_BSP_NETWORK_DRIVER_NAME,
- RTEMS_BSP_NETWORK_DRIVER_ATTACH
-@};
-struct rtems_bsdnet_config rtems_bsdnet_config = @{
- &netdriver_config,
- rtems_bsdnet_do_bootp,
-@};
-@end example
-
-
-@subsection Network initialization
-The networking tasks must be started before any network I/O operations
-can be performed. This is done by calling:
-
-
-@example
-rtems_bsdnet_initialize_network ();
-@end example
-
-This function is declared in @code{rtems/rtems_bsdnet.h}.
-t returns 0 on success and -1 on failure with an error code
-in @code{errno}. It is not possible to undo the effects of
-a partial initialization, though, so the function can be
-called only once irregardless of the return code. Consequently,
-if the condition for the failure can be corrected, the
-system must be reset to permit another network initialization
-attempt.
-
-
-
-@section Application Programming Interface
-
-The RTEMS network package provides almost a complete set of BSD network
-services. The network functions work like their BSD counterparts
-with the following exceptions:
-
-@itemize @bullet
-@item A given socket can be read or written by only one task at a time.
-
-@item The @code{select} function only works for file descriptors associated
-with sockets.
-
-@item You must call @code{openlog} before calling any of the @code{syslog} functions.
-
-@item @b{Some of the network functions are not thread-safe.}
-For example the following functions return a pointer to a static
-buffer which remains valid only until the next call:
-
-@table @code
-@item gethostbyaddr
-@item gethostbyname
-@item inet_ntoa
-(@code{inet_ntop} is thread-safe, though).
-@end table
-
-@item The RTEMS network package gathers statistics.
-
-@item Addition of a mechanism to "tap onto" an interface
-and monitor every packet received and transmitted.
-
-@item Addition of @code{SO_SNDWAKEUP} and @code{SO_RCVWAKEUP} socket options.
-
-@end itemize
-
-Some of the new features are discussed in more detail in the following
-sections.
-
-@subsection Network Statistics
-
-There are a number of functions to print statistics gathered by
-the network stack.
-These function are declared in @code{rtems/rtems_bsdnet.h}.
-
-@table @code
-@item rtems_bsdnet_show_if_stats
-Display statistics gathered by network interfaces.
-
-@item rtems_bsdnet_show_ip_stats
-Display IP packet statistics.
-
-@item rtems_bsdnet_show_icmp_stats
-Display ICMP packet statistics.
-
-@item rtems_bsdnet_show_tcp_stats
-Display TCP packet statistics.
-
-@item rtems_bsdnet_show_udp_stats
-Display UDP packet statistics.
-
-@item rtems_bsdnet_show_mbuf_stats
-Display mbuf statistics.
-
-@item rtems_bsdnet_show_inet_routes
-Display the routing table.
-
-@end table
-
-@subsection Tapping Into an Interface
-
-RTEMS add two new ioctls to the BSD networking code:
-SIOCSIFTAP and SIOCGIFTAP. These may be used to set and get a
-@i{tap function}. The tap function will be called for every
-Ethernet packet received by the interface.
-
-These are called like other interface ioctls, such as SIOCSIFADDR.
-When setting the tap function with SIOCSIFTAP, set the ifr_tap field
-of the ifreq struct to the tap function. When retrieving the tap
-function with SIOCGIFTAP, the current tap function will be returned in
-the ifr_tap field. To stop tapping packets, call SIOCSIFTAP with a
-ifr_tap field of 0.
-
-The tap function is called like this:
-
-@example
-int tap (struct ifnet *, struct ether_header *, struct mbuf *)
-@end example
-
-The tap function should return 1 if the packet was fully handled, in
-which case the caller will simply discard the mbuf. The tap function
-should return 0 if the packet should be passed up to the higher
-networking layers.
-
-The tap function is called with the network semaphore locked. It must
-not make any calls on the application levels of the networking level
-itself. It is safe to call other non-networking RTEMS functions.
-
-@subsection Socket Options
-
-RTEMS adds two new @code{SOL_SOCKET} level options for @code{setsockopt} and
-@code{getsockopt}: @code{SO_SNDWAKEUP} and @code{SO_RCVWAKEUP}. For both, the
-option value should point to a sockwakeup structure. The sockwakeup
-structure has the following fields:
-
-@example
-@group
- void (*sw_pfn) (struct socket *, caddr_t);
- caddr_t sw_arg;
-@end group
-@end example
-
-These options are used to set a callback function to be called when, for
-example, there is
-data available from the socket (@code{SO_RCVWAKEUP}) and when there is space
-available to accept data written to the socket (@code{SO_SNDWAKEUP}).
-
-If @code{setsockopt} is called with the @code{SO_RCVWAKEUP} option, and the
-@code{sw_pfn} field is not zero, then when there is data
-available to be read from
-the socket, the function pointed to by the @code{sw_pfn} field will be
-called. A pointer to the socket structure will be passed as the first
-argument to the function. The @code{sw_arg} field set by the
-@code{SO_RCVWAKEUP} call will be passed as the second argument to the function.
-
-If @code{setsockopt} is called with the @code{SO_SNDWAKEUP}
-function, and the @code{sw_pfn} field is not zero, then when
-there is space available to accept data written to the socket,
-the function pointed to by the @code{sw_pfn} field
-will be called. The arguments passed to the function will be as with
-@code{SO_SNDWAKEUP}.
-
-When the function is called, the network semaphore will be locked and
-the callback function runs in the context of the networking task.
-The function must be careful not to call any networking functions. It
-is OK to call an RTEMS function; for example, it is OK to send an
-RTEMS event.
-
-The purpose of these callback functions is to permit a more efficient
-alternative to the select call when dealing with a large number of
-sockets.
-
-The callbacks are called by the same criteria that the select
-function uses for indicating "ready" sockets. In Stevens @cite{Unix
-Network Programming} on page 153-154 in the section "Under what Conditions
-Is a Descriptor Ready?" you will find the definitive list of conditions
-for readable and writable that also determine when the functions are
-called.
-
-When the number of received bytes equals or exceeds the socket receive
-buffer "low water mark" (default 1 byte) you get a readable callback. If
-there are 100 bytes in the receive buffer and you only read 1, you will
-not immediately get another callback. However, you will get another
-callback after you read the remaining 99 bytes and at least 1 more byte
-arrives. Using a non-blocking socket you should probably read until it
-produces error EWOULDBLOCK and then allow the readable callback to tell
-you when more data has arrived. (Condition 1.a.)
-
-For sending, when the socket is connected and the free space becomes at
-or above the "low water mark" for the send buffer (default 4096 bytes)
-you will receive a writable callback. You don't get continuous callbacks
-if you don't write anything. Using a non-blocking write socket, you can
-then call write until it returns a value less than the amount of data
-requested to be sent or it produces error EWOULDBLOCK (indicating buffer
-full and no longer writable). When this happens you can
-try the write again, but it is often better to go do other things and
-let the writable callback tell you when space is available to send
-again. You only get a writable callback when the free space transitions
-to above the "low water mark" and not every time you
-write to a non-full send buffer. (Condition 2.a.)
-
-The remaining conditions enumerated by Stevens handle the fact that
-sockets become readable and/or writable when connects, disconnects and
-errors occur, not just when data is received or sent. For example, when
-a server "listening" socket becomes readable it indicates that a client
-has connected and accept can be called without blocking, not that
-network data was received (Condition 1.c).
-
-@subsection Adding an IP Alias
-
-The following code snippet adds an IP alias:
-
-@example
-void addAlias(const char *pName, const char *pAddr, const char *pMask)
-@{
- struct ifaliasreq aliasreq;
- struct sockaddr_in *in;
-
- /* initialize alias request */
- memset(&aliasreq, 0, sizeof(aliasreq));
- sprintf(aliasreq.ifra_name, pName);
-
- /* initialize alias address */
- in = (struct sockaddr_in *)&aliasreq.ifra_addr;
- in->sin_family = AF_INET;
- in->sin_len = sizeof(aliasreq.ifra_addr);
- in->sin_addr.s_addr = inet_addr(pAddr);
-
- /* initialize alias mask */
- in = (struct sockaddr_in *)&aliasreq.ifra_mask;
- in->sin_family = AF_INET;
- in->sin_len = sizeof(aliasreq.ifra_mask);
- in->sin_addr.s_addr = inet_addr(pMask);
-
- /* call to setup the alias */
- rtems_bsdnet_ifconfig(pName, SIOCAIFADDR, &aliasreq);
-@}
-@end example
-
-Thanks to @uref{mailto:mikes@@poliac.com,Mike Seirs} for this example
-code.

-the command @code{route add default gw yyy.yyy.yyy.yyy}:
-
-@example
-void mon_ifconfig(int argc, char *argv[], unsigned32 command_arg,
- bool verbose)

-Thanks to @uref{mailto:jtm@@smoothmsmoothie.com,Jay Monkman} for this example
-code.

-@subsection Time Synchronization Using NTP
-
-@example
-int rtems_bsdnet_synchronize_ntp (int interval, rtems_task_priority priority);
-@end example
-
-If the interval argument is 0 the routine synchronizes the RTEMS time-of-day
-clock with the first NTP server in the rtems_bsdnet_ntpserve array and
-returns. The priority argument is ignored.
-
-If the interval argument is greater than 0, the routine also starts an
-RTEMS task at the specified priority and polls the NTP server every
-`interval' seconds. NOTE: This mode of operation has not yet been
-implemented.
-
-On successful synchronization of the RTEMS time-of-day clock the routine
-returns 0. If an error occurs a message is printed and the routine returns -1
-with an error code in errno.
-There is no timeout -- if there is no response from an NTP server the
-routine will wait forever.

-The transmit task for each network interface is normally blocked waiting
-for a packet to arrive in the transmit queue. Once a packet arrives, the
-transmit task may block waiting for an event from the transmit interrupt
-handler. The transmit interrupt handler sends an RTEMS event to the transmit
-task to indicate that transmit hardware resources have become available.
-
-The receive task for each network interface is normally blocked waiting
-for an event from the receive interrupt handler. When this event is received
-the receive task reads the packet and forwards it to the network stack
-for subsequent processing by the network task.
-
-The network task processes incoming packets and takes care of
-timed operations such as handling TCP timeouts and
-aging and removing routing table entries.
-
-The `Network code' contains routines which may run in the context of
-the user application tasks, the interface receive task or the network task.
-A network semaphore ensures that
-the data structures manipulated by the network code remain consistent.

-
-This document describes the RTEMS specific parts of the FreeBSD TCP/IP
-stack. Much of this documentation was written by Eric Norum
-(@email{eric@@skatter.usask.ca})
-of the Saskatchewan Accelerator Laboratory
-who also ported the FreeBSD TCP/IP stack to RTEMS.
-
-The following is a list of resources which should be useful in trying
-to understand Ethernet:
-
-@itemize @bullet
-
-@item @cite{Charles Spurgeon's Ethernet Web Site}
-
-"This site provides extensive information about Ethernet
-(IEEE 802.3) local area network (LAN) technology. Including
-the original 10 Megabit per second (Mbps) system, the 100 Mbps
-Fast Ethernet system (802.3u), and the Gigabit Ethernet system (802.3z)."

-@item @cite{TCP/IP Illustrated, Volume 1 : The Protocols} by
-by W. Richard Stevens (ISBN: 0201633469)
-
-This book provides detailed introduction to TCP/IP and includes diagnostic
-programs which are publicly available.
-
-@item @cite{TCP/IP Illustrated, Volume 2 : The Implementation} by W. Richard
-Stevens and Gary Wright (ISBN: 020163354X)
-
-This book focuses on implementation issues regarding TCP/IP. The
-treat for RTEMS users is that the implementation covered is the BSD
-stack with most of the source code described in detail.
-
-@item @cite{UNIX Network Programming, Volume 1 : 2nd Edition} by W. Richard
-Stevens (ISBN: 0-13-490012-X)
-
-This book describes how to write basic TCP/IP applications, again with primary
-focus on the BSD stack.

-@section RTEMS FTP Daemon
-
-The RTEMS FTPD is a complete file transfer protocol (FTP) daemon
-which can store, retrieve, and manipulate files on the local
-filesystem. In addition, the RTEMS FTPD provides ``hooks''
-which are actions performed on received data. Hooks are useful
-in situations where a destination file is not necessarily
-appropriate or in cases when a formal device driver has not yet
-been implemented.
-
-This server was implemented and documented by Jake Janovetz
-(janovetz@@tempest.ece.uiuc.edu).
-
-@subsection Configuration Parameters
-
-The configuration structure for FTPD is as follows:
-
-@example
-struct rtems_ftpd_configuration
-@{
- rtems_task_priority priority; /* FTPD task priority */
- unsigned long max_hook_filesize; /* Maximum buffersize */
- /* for hooks */
- int port; /* Well-known port */
- struct rtems_ftpd_hook *hooks; /* List of hooks */
-@};
-@end example
-
-The FTPD task priority is specified with @code{priority}. Because
-hooks are not saved as files, the received data is placed in an
-allocated buffer. @code{max_hook_filesize} specifies the maximum
-size of this buffer. Finally, @code{hooks} is a pointer to the
-configured hooks structure.
-
-@subsection Initializing FTPD (Starting the daemon)
-
-Starting FTPD is done with a call to @code{rtems_initialize_ftpd()}.
-The configuration structure must be provided in the application
-source code. Example hooks structure and configuration structure
-folllow.
-
-@example
-struct rtems_ftpd_hook ftp_hooks[] =
- @{
- @{"untar", Untar_FromMemory@},
- @{NULL, NULL@}
- @};
-
-struct rtems_ftpd_configuration rtems_ftpd_configuration =
- @{
- 40, /* FTPD task priority */
- 512*1024, /* Maximum hook 'file' size */
- 0, /* Use default port */
- ftp_hooks /* Local ftp hooks */
- @};
-@end example
-
-Specifying 0 for the well-known port causes FTPD to use the
-UNIX standard FTPD port (21).
-
-@subsection Using Hooks
-
-In the example above, one hook was installed. The hook causes
-FTPD to call the function @code{Untar_FromMemory} when the
-user sends data to the file @code{untar}. The prototype for
-the @code{untar} hook (and hooks, in general) is:
-
-@example
- int Untar_FromMemory(unsigned char *tar_buf, unsigned long size);
-@end example
-
-An example FTP transcript which exercises this hook is:
-
-@example
-220 RTEMS FTP server (Version 1.0-JWJ) ready.
-Name (dcomm0:janovetz): John Galt
-230 User logged in.
-Remote system type is RTEMS.
-ftp> bin
-200 Type set to I.
-ftp> dir
-200 PORT command successful.

-226 Transfer complete.
-ftp> put html.tar untar
-local: html.tar remote: untar
-200 PORT command successful.
-150 BINARY data connection.
-210 File transferred successfully.
-471040 bytes sent in 0.48 secs (9.6e+02 Kbytes/sec)
-ftp> dir
-200 PORT command successful.
-150 ASCII data connection for LIST.
-drwxrwx--x 0 0 268 dev
-drwxrwx--x 0 0 0 TFTP
-drwxrwx--x 0 0 3484 public_html
-226 Transfer complete.
-ftp> quit
-221 Goodbye.

-@chapter Testing the Driver
-
-@section Preliminary Setup
-
-The network used to test the driver should include at least:
-
-@itemize @bullet
-
-@item The hardware on which the driver is to run.
-It makes testing much easier if you can run a debugger to control
-the operation of the target machine.
-
-@item An Ethernet network analyzer or a workstation with an
-`Ethernet snoop' program such as @code{ethersnoop} or
-@code{tcpdump}.
-
-@item A workstation.
-
-@end itemize
-
-During early debug, you should consider putting the target, workstation,
-and snooper on a small network by themselves. This offers a few
-advantages:
-
-@itemize @bullet
-
-@item There is less traffic to look at on the snooper and for the target
-to process while bringing the driver up.
-
-@item Any serious errors will impact only your small network not a building
-or campus network. You want to avoid causing any unnecessary problems.
-
-@item Test traffic is easier to repeatably generate.
-
-@item Performance measurements are not impacted by other systems on
-the network.
-
-@end itemize
-
-@section Debug Output
-
-There are a number of sources of debug output that can be enabled
-to aid in tracing the behavior of the network stack. The following
-is a list of them:
-
-@itemize @bullet
-
-@item mbuf activity
-
-There are commented out calls to @code{printf} in the file
-@code{sys/mbuf.h} in the network stack code. Uncommenting
-these lines results in output when mbuf's are allocated
-and freed. This is very useful for finding memory leaks.
-
-@item TX and RX queuing
-
-There are commented out calls to @code{printf} in the file
-@code{net/if.h} in the network stack code. Uncommenting
-these lines results in output when packets are placed
-on or removed from one of the transmit or receive packet
-queues. These queues can be viewed as the boundary line
-between a device driver and the network stack. If the
-network stack is enqueuing packets to be transmitted that
-the device driver is not dequeuing, then that is indicative
-of a problem in the transmit side of the device driver.
-Conversely, if the device driver is enqueueing packets
-as it receives them (via a call to @code{ether_input}) and
-they are not being dequeued by the network stack,
-then there is a problem. This situation would likely indicate
-that the network server task is not running.
-
-@item TCP state transitions
-
-In the unlikely event that one would actually want to see
-TCP state transitions, the @code{TCPDEBUG} macro can be defined
-in the file @code{opt_tcpdebug.h}. This results in the routine
-@code{tcp_trace()} being called by the network stack and
-the state transitions logged into the @code{tcp_debug} data
-structure. If the variable @code{tcpconsdebug} in the file
-@code{netinet/tcp_debug.c} is set to 1, then the state transitions
-will also be printed to the console.
-
-@end itemize
-
-@section Monitor Commands
-
-There are a number of command available in the shell / monitor
-to aid in tracing the behavior of the network stack. The following
-is a list of them:
-
-@itemize @bullet
-
-@item @code{inet}
-
-This command shows the current routing information for the TCP/IP stack. Following is an
-example showing the output of this command.
-
-@example
-Destination Gateway/Mask/Hw Flags Refs Use Expire Interface
-10.0.0.0 255.0.0.0 U 0 0 17 smc1
-127.0.0.1 127.0.0.1 UH 0 0 0 lo0
-@end example
-
-In this example, there is only one network interface with an IP address of 10.8.1.1. This
-link is currently not up.
-
-Two routes that are shown are the default routes for the Ethernet interface (10.0.0.0) and the
-loopback interface (127.0.0.1).
-
-Since the stack comes from BSD, this command is very similar to the netstat command. For more
-details on the network routing please look the following
-URL: (@url{http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-routing.html})
-
-For a quick reference to the flags, see the table below:
-
-@table @samp
-@item U
-Up: The route is active.
-@item H
-Host: The route destination is a single host.
-@item G
-Gateway: Send anything for this destination on to this remote system, which
-will figure out from there where to send it.
-@item S
-Static: This route was configured manually, not automatically generated by the
-system.
-@item C
-Clone: Generates a new route based upon this route for machines we connect
-to. This type of route is normally used for local networks.
-@item W
-WasCloned: Indicated a route that was auto-configured based upon a local area
-network (Clone) route.
-@item L
-Link: Route involves references to Ethernet hardware.
-@end table
-
-@item @code{mbuf}
-
-This command shows the current MBUF statistics. An example of the command is shown below:
-
-@example
-************ MBUF STATISTICS ************
-mbufs:4096 clusters: 256 free: 241
-drops: 0 waits: 0 drains: 0
- free:4080 data:16 header:0 socket:0
- pcb:0 rtable:0 htable:0 atable:0
- soname:0 soopts:0 ftable:0 rights:0
- ifaddr:0 control:0 oobdata:0
-@end example
-
-@item @code{if}
-
-This command shows the current statistics for your Ethernet driver as long as the ioctl hook
-@code{SIO_RTEMS_SHOW_STATS} has been implemented. Below is an example:
-
-@example
-************ INTERFACE STATISTICS ************
-***** smc1 *****
-Ethernet Address: 00:12:76:43:34:25
-Address:10.8.1.1 Broadcast Address:10.255.255.255 Net mask:255.0.0.0

-@end example
-
-@item @code{ip}
-
-This command show the IP statistics for the currently configured interfaces.
-
-@item @code{icmp}
-
-This command show the ICMP statistics for the currently configured interfaces.
-
-@item @code{tcp}
-
-This command show the TCP statistics for the currently configured interfaces.
-
-@item @code{udp}
-
-This command show the UDP statistics for the currently configured interfaces.
-
-@end itemize
-
-
-@section Driver basic operation
-
-The network demonstration program @code{netdemo} may be used for these tests.
-
-@itemize @bullet
-
-@item Edit @code{networkconfig.h} to reflect the values for your network.
-
-@item Start with @code{RTEMS_USE_BOOTP} not defined.
-
-@item Edit @code{networkconfig.h} to configure the driver
-with an
-explicit Ethernet and Internet address and with reception of
-broadcast packets disabled:
-
-Verify that the program continues to run once the driver has been attached.
-
-@item Issue a @samp{u} command to send UDP
-packets to the `discard' port.
-Verify that the packets appear on the network.
-
-@item Issue a @samp{s} command to print the network and driver statistics.
-
-@item On a workstation, add a static route to the target system.
-
-@item On that same workstation try to `ping' the target system.
-Verify that the ICMP echo request and reply packets appear on the net.
-
-@item Remove the static route to the target system.
-Modify @code{networkconfig.h} to attach the driver
-with reception of broadcast packets enabled.
-Try to `ping' the target system again.
-Verify that ARP request/reply and ICMP echo request/reply packets appear
-on the net.
-
-@item Issue a @samp{t} command to send TCP
-packets to the `discard' port.
-Verify that the packets appear on the network.
-
-@item Issue a @samp{s} command to print the network and driver statistics.
-
-@item Verify that you can telnet to ports 24742
-and 24743 on the target system from one or more
-workstations on your network.
-
-@end itemize
-
-@section BOOTP/DHCP operation
-
-Set up a BOOTP/DHCP server on the network.
-Set define @code{RTEMS USE_BOOT} in @code{networkconfig.h}.
-Run the @code{netdemo} test program.
-Verify that the target system configures itself from the BOOTP/DHCP server and
-that all the above tests succeed.
-
-@section Stress Tests
-
-Once the driver passes the tests described in the previous section it should
-be subjected to conditions which exercise it more
-thoroughly and which test its error handling routines.
-
-@subsection Giant packets
-
-@itemize @bullet
-@item Recompile the driver with @code{MAXIMUM_FRAME_SIZE} set to
-a smaller value, say 514.
-
-@item `Ping' the driver from another workstation and verify
-that frames larger than 514 bytes are correctly rejected.
-
-@item Recompile the driver with @code{MAXIMUM_FRAME_SIZE} restored to 1518.
-@end itemize
-
-@subsection Resource Exhaustion
-
-@itemize @bullet
-@item Edit @code{networkconfig.h}
-so that the driver is configured with just two receive and transmit descriptors.
-
-@item Compile and run the @code{netdemo} program.
-
-@item Verify that the program operates properly and that you can
-still telnet to both the ports.
-
-@item Display the driver statistics (Console `@code{s}' command or telnet
-`control-G' character) and verify that:
-
-@enumerate
-
-@item The number of transmit interrupts is non-zero.
-This indicates that all transmit descriptors have been in use at some time.
-
-@item The number of missed packets is non-zero.
-This indicates that all receive descriptors have been in use at some time.
-
-@end enumerate
-
-@end itemize
-
-@subsection Cable Faults
-
-@itemize @bullet
-@item Run the @code{netdemo} program.
-
-@item Issue a `@code{u}' console command to make the target machine transmit
-a bunch of UDP packets.
-
-@item While the packets are being transmitted, disconnect and reconnect the
-network cable.
-
-@item Display the network statistics and verify that the driver has
-detected the loss of carrier.
-
-@item Verify that you can still telnet to both ports on the target machine.
-
-@end itemize
-
-@subsection Throughput
-
-Run the @code{ttcp} network benchmark program.
-Transfer large amounts of data (100's of megabytes) to and from the target
-system.
-
-The procedure for testing throughput from a host to an RTEMS target
-is as follows:
-
-@enumerate
-@item Download and start the ttcp program on the Target.
-
-@item In response to the @code{ttcp} prompt, enter @code{-s -r}. The
-meaning of these flags is described in the @code{ttcp.1} manual page
-found in the @code{ttcp_orig} subdirectory.
-
-@item On the host run @code{ttcp -s -t <<insert the hostname or IP address of
-the Target here>>}
-
-@end enumerate
-
-
-The procedure for testing throughput from an RTEMS target
-to a Host is as follows:
-
-@enumerate
-@item On the host run @code{ttcp -s -r}.
-
-@item Download and start the ttcp program on the Target.
-
-@item In response to the @code{ttcp} prompt, enter @code{-s -t <<insert
-the hostname or IP address of the Target here>>}. You need to type the
-IP address of the host unless your Target is talking to your Domain Name
-Server.
-
-@end enumerate
-
-To change the number of buffers, the buffer size, etc. you just add the
-extra flags to the @code{-t} machine as specified in the @code{ttcp.1}
-manual page found in the @code{ttcp_orig} subdirectory.
