[vortex] 3c900 -COMBO Media Type Problems

[Dohan]

I have tried a few setting with the mii-diag program. Am I supposed to be
using the -A or the -F flag? I can't seem to change the line that says
"Speed fixed at 10 mbps, half-duplex".  I am also trying to get the DOS
config working, no luck with that yet...figures :)  Anyways, this is the
feedback from mii-diag. Maybe this will help.

root@linux:/home/dohan/3c90x-1.0.0 > ./mii-diag
Using the default interface 'eth0'.
