[ES40-developers] Patch: DEC21143 support for Tru64

[Brian W. <bdw...@in...>]

It looks like the SROM on the NIC has to be properly checksummed before
Tru64 will use it.  I found the tru64 device driver kit sample files
online which contained the tulip driver as a sample!  I've attached the
files in case there are other problems we have later with the NIC.

After copying the crc routine and working it into the ResetNIC function,
tru64 likes the device:

tu0: DECchip 21143: Revision: 3.0
tu0: auto negotiation capable device
tu0 at pci0 slot 4
tu0: DEC TULIP (10/100) Ethernet Interface, hardware address: 08-00-2B-E5-40-00
tu0: no console mode: defaulting to 10BaseT (UTP) port: half duplex


For tcp/ip it doesn't seem to connect to the outside world, but I can
run ifconfig and configure it without errors.
