This driver has been developed for use with -FreeBSD, version 5.x. - -For questions related to hardware requirements, refer to the documentation -supplied with your Intel PRO/1000 adapter. All hardware requirements listed -apply to use with FreeBSD. - - -Identifying Your Adapter -======================== - -For information on how to identify your adapter, go to the Adapter & -Driver ID Guide at: - -http://support.intel.com/support/network/adapter/pro100/21397.htm - - -For the latest Intel network drivers for FreeBSD, see: - -http://appsr.intel.com/scripts-df/support_intel.asp - - -NOTE: Mobile adapters are not fully supported. - - -Building and Installation -========================= - -NOTE: The driver can be installed as a dynamic loadable kernel module or - compiled into the kernel. You must have kernel sources installed in - order to compile the driver module. - -In the instructions below, x.x.x is the driver version as indicated in the -name of the driver tar file. - -1. Move the base driver tar file to the directory of your choice. For - example, use /home/username/em or /usr/local/src/em. - -2. Untar/unzip the archive: - - tar xvfz em-x.x.x.tar.gz - - This will create an em-x.x.x directory. - -3. To create a loadable module, perform the following steps. - NOTE: To compile the driver into the kernel, go directly to step 4. - - a. To compile the module - - cd em-x.x.x - make - - b. To install the compiled module in system directory: - - make install - - c. If you want the driver to load automatically when the system is booted: - - 1. Edit /boot/loader.conf, and add the following line: - - if_em_load="YES" - -4. To compile the driver into the kernel: - - cd em-x.x.x/src - - cp if_em* /usr/src/sys/dev/em - - cp Makefile.kernel /usr/src/sys/modules/em/Makefile - - Edit the /usr/src/sys/conf/files.i386 file, and add the following lines only if - they don't already exist: - - dev/em/if_em.c optional em - - dev/em/if_em_hw.c optional em - - Remove the following lines from the /usr/src/sys/conf/files.i386 file, - if they exist: - - dev/em/if_em_fxhw.c optional em - dev/em/if_em_phy.c optional em - - Edit the kernel configuration file (i.e., GENERIC or MYKERNEL) in - /usr/src/sys/i386/conf, and ensure the following line is present: - - device em - - Compile and install the kernel. The system must be rebooted for the kernel - updates to take effect. For additional information on compiling the - kernel, consult the FreeBSD operating system documentation. - -5. To assign an IP address to the interface, enter the following: - - ifconfig em - -6. Verify that the interface works. Enter the following, where - is the IP address for another machine on the same subnet as the interface - that is being tested: - - ping - -7. To configure the IP address to remain after reboot, edit /etc/rc.conf, - and create the appropriate ifconfig_ementry: - - ifconfig_em="" - - Example usage: - - ifconfig_em0="inet 192.168.10.1 netmask 255.255.255.0" - - NOTE: For assistance, see the ifconfig man page. - - -Speed and Duplex Configuration -============================== - -By default, the adapter auto-negotiates the speed and duplex of the -connection. If there is a specific need, the ifconfig utility can be used to -configure the speed and duplex settings on the adapter. Example usage: - - ifconfig em media 100baseTX mediaopt - full-duplex - - NOTE: Only use mediaopt to set the driver to full-duplex. If mediaopt is - not specified and you are not running at gigabit speed, the driver - defaults to half-duplex. - - -This driver supports the following media type options: - - autoselect - Enables auto-negotiation for speed and duplex. - - 10baseT/UTP - Sets speed to 10 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. - - 100baseTX - Sets speed to 100 Mbps. Use the ifconfig mediaopt - option to select full-duplex mode. - - 1000baseTX - Sets speed to 1000 Mbps. In this case, the driver - supports only full-duplex mode. - - 1000baseSX - Sets speed to 1000 Mbps. In this case, the driver - supports only full-duplex mode. - -For more information on the ifconfig utility, see the ifconfig man page. - - -Additional Configurations -========================= - -The driver supports Transmit/Receive Checksum Offload and Jumbo Frames on -all but the 82542-based adapters. For specific adapters, refer to the -Identifying Your Adapter section. - - Jumbo Frames - ------------ - To enable Jumbo Frames, use the ifconfig utility to increase the MTU - beyond 1500 bytes. - - NOTES: Only enable Jumbo Frames if your network infrastructure supports - them. - - The Jumbo Frames setting on the switch must be set to at least - 22 bytes larger than that of the MTU. - - The Intel PRO/1000 PM Network Connection does not support jumbo - frames. - - - The Jumbo Frames MTU range for Intel Adapters is 1500 to 16114. The default - MTU range is 1500. To modify the setting, enter the following: - - ifconfig em mtu 9000 - - To confirm the MTU used between two specific devices, use: - - route get - - VLANs - ----- - To create a new VLAN interface: - - ifconfig create - - To associate the VLAN interface with a physical interface and - assign a VLAN ID, IP address, and netmask: - - ifconfig netmask vlan - vlandev - - Example: - - ifconfig vlan10 10.0.0.1 netmask 255.255.255.0 vlan10 vlandev em0 - - In this example, all packets will be marked on egress with 802.1Q VLAN - tags, specifying a VLAN ID of 10. - - To remove a VLAN interface: - - ifconfig destroy - - Polling - ------- - NOTES: DEVICE POLLING is only valid for non-SMP kernels. - - The driver has to be compiled into the kernel for DEVICE POLLING to be - enabled in the driver. - - To enable polling in the driver, add the following options to the kernel - configuration, and then recompile the kernel: - - options DEVICE_POLLING - options HZ=1000 - - At runtime use: - sysctl kern.polling.enable=1 to turn polling on - Use: - sysctl kern.polling.enable=0 to turn polling off - - Checksum Offload - ---------------- - Checksum offloading is not supported on 82542 Gigabit adapters. - - Checksum offloading supports both TCP and UDP packets and is - supported for both transmit and receive. - - Checksum offloading can be enabled or disabled using ifconfig. - Both transmit and receive offloading will be either enabled or - disabled together. You cannot enable/disable one without the other. - - To enable checksum offloading: - - ifconfig rxcsum - - To disable checksum offloading: - - ifconfig -rxcsum - - To confirm the current setting: - - ifconfig - - Look for the presence or absence of the following line: - - options=3 - - See the ifconfig man page for further information. - -Known Limitations -================= - - There are known performance issues with this driver when running UDP traffic - with Jumbo Frames. - - There is a known compatibility issue where time to link is slow or link is not - established between 82541/82547 controllers and some switches. Known switches - include: - Planex FXG-08TE - I-O Data ETG-SH8 - - The driver can be compiled with the following changes: - - Edit ./em.x.x.x/src/if_em.h to uncomment the #define EM_MASTER_SLAVE - from within the comments. For example, change from: - - /* #define EM_MASTER_SLAVE 2 */ - to: - #define EM_MASTER_SLAVE 2 - - Use one of the following options: - 1 = Master mode - 2 = Slave mode - 3 = Auto master/slave - Setting 2 is recommended. - - Recompile the module: - a. To compile the module - cd em-x.x.x - make clean - make - - b. To install the compiled module in system directory: - make install - - -Support -======= - -For general information and support, go to the Intel support website at: - - http://support.intel.com - -If an issue is identified, support is through email only at: -freebsdnic@mailbox.intel.com - -License -======= - -This software program is released under the terms of a license agreement -between you ('Licensee') and Intel.
