-Networking with HDLC
-====================
-
-Author: Andy Dachs <a.dachs@sstl.co.uk>
-Date:	31st August 2001
-Surrey Satellite Technology Limited
-
-
-The network support in this BSP is not Ethernet support. The
-"network" referred to here is a point to point HDLC communication link.
-The ADS board does have a 10/100 ethernet port and it would be nice to
-get support for that added.
-
-My requirement is for a WAN so I need the ability to send IP frames over
-HDLC.  Ultimately this will end up as frame relay support but in the meantime
-I'm simply wrapping up the IP packet inside an HDLC frame.  There is no
-addressing mechanism or mac address attached to the start of the frame.
-
-This is what is physically transmitted:
-<FLAG><IP Frame><CRC><FLAG>
-
-
-The physical link consists of four lines,
-TX DATA	:	Data transmitted
-TX CLOCK:	Clock for transmitted data.  Data source provides clock.
-RX DATA : 	Received data
-RX CLOCK:	Clock for received data.  Data sink accepts clock.
-
-To connect two entities you require a NULL modem arrangement, i.e. TX data
-and Tx clock from one end go into RX data and Rx clock on the other end.
-
-The MPC8260ADS side of the link is implemented using SCC3 in HDLC mode. The
-TX clock is generated by BRG4.  The RX clock in input to the board on the CLK5
-input.  I built a LVTTL to RS422 converter.
-
-The other end of the link is a Windows NT PC with WANic400 synchronous
-communication card.  We bought the card from ImageStream
-(http://www.imagestream.com/WANic400.html).  You also need the NT
-drivers and a cable.  There are other distributors but I found these
-guys helpful - and they also do Linux drivers.
-
-The NT WANic driver has a number of modes, one of which is ethernet emulation.
-This mode is what is needed to transport IP packets in HDLC frames.
-
-In libnetworking/net you will find a file called if_hdlcsubr.c containing
-the hdlc_input and hdlc_output routines required by network.c.  This file was
-created by taking out the addressing mechanisms from if_ethersubr.c in the
-same directory.  There are probably neater ways to do this <any
-contributions welcome here>.

- * Created from if_ethersubr.c by Andy Dachs <a.dachs@sstl.co.uk>
- * Surrey Satellite Technology Limited (SSTL), 2001
- * Modified (hacked) to support IP frames transmitted over HDLC. This
- * all needs tidying up in future but it does actually work for point
- * to point communications. I have an SDL WANic400 synchronous
- * communications card that comes with Windows NT drivers.  The drivers
- * support a mode that they call "Ethernet Emulation".  That simply
- * puts the IP frame in an HDLC frame without any ethernet header. i.e.
- * <HDLC Flag><IpFrame><CRC><HDLC Flag>.  There is no addressing beyond
- * the IP header information so is only suitable for point to point links
- * with a single protocol. "At some point" I will add a Frame Relay header
- * but at the moment I have difficulties getting the WANic card driver's
- * Frame Relay driver to work.
