Very Computer

I've been unable to get my 3c595 card to use 100baseTx-FD.  I have attempted
to force this with the mii-tool using

mii-tool -F 100baseTx-FD eth0

or by loading the module and specifying that speed.  I loaded the module
with the following

insmod 3c59x debug=6 options=4,4,4 full_duplex=1,1,1

Here is some relevant output from my system that may help to determine what
the exact problem is.

I changed the HWaddr and IP since they are not important to this discussion.

I also see the following output in /var/log/messages

I haven't been able to find any way of getting this card to work.  I've made
sure that the cables are seated correctly and I'm using a 3com 10/100
Switch with autonegotiation enabled.  I've even forced the speed/duplexity
on the switch with no luck.

I'm hoping someone may have a better answer to this problem.

Try the -v for more information.

I assume you have already Googled for this. ISTM that autonegotiation
fails, so the driver falls back to the safest default.

Have you done something wacky with your kernel configuration? Try using
your distro's kernel and modules. If you ARE using a distro kernel and
Google turned up empty, this would be an issue to take to the driver's
maintainer, or a more specialised forum if it exists.
