[vortex] A 3c905B behaving strange

[Antti T J Granqvist]

I moved the card to the router(eth0), also running Linux RH7.3. Now
filetransfers from any local computers to the router hang. Thus the
problem seems to move along with the card. After cold boot, without any
driver module parameters I have following reports:

Now I try to set the card to half-duplex by
rmmod 3c59x
and
insmod 3c59x debug=3 full_duplex=0

Indicates that the card is still full-duplex. Is the card broken somehow,
or why did the setting  not change?

Also as I mentioned earlier, at cold boot _THIS_ card makes the hub jam
until the driver is loaded.

Any help is appreciated.
