[eepro100] Problem with eepro100 driver, ES40 SMP

[Craig Tierney]

Here is a followup to my own post.

The latest version (v1.13) of the eepro100 driver does work for my
ES40s now.  My problem ended up being that I was compiling
the driver incorrectly.  The options at the bottom of the eepro100.c
are not correct for Alpha.  Although I added the -ffixed-8 option,
more ware missing.

In the file netdrivers-2.1.6.rpm, the Makefile adds a couple of
options for the Alpha architecture:

    CFLAGS+=-pipe -mno-fp-regs -ffixed-8 -mcpu=ev5

In a nutshell:  Get the rpm and use the makefile.  It will get the
flags right for your architecture.

Things are better now. I can run 8k packets with UDP.  Other issues
are preventing me from larger packets and TCP.
