[eepro100] is there a working driver for linux alpha

I have 144 alpha nodes, 2 way SMP each.  They all have the DE600
compaq card installed (eepro100 compatible).  I am assuming you
have the same one.

We are using the same ethernet driver, but we are using the 2.4.14
kernel.  We are not having any problems.  

Every card and every port on every switch is locked to 100FDX.
We have had not problems with this setup.

If you want to try the e100 driver, I suggest that you download
the latest redhat kernel.  It is included in their 3rd party drivers.
I have never tried it myself, but I suspect that you might have
a chance at getting that working.
