[tulip] Re: ANA 6944A/TX RX errors

[Christian Birchinger]

I booted the System with the 2.4.16 builtin tulip driver and
a small fix which was posted to this list.
Since then i cannot reproduce this error. I rebooted into the
kernel with the 0.93 modules now and it works too.
It seems that i can't provide the requested infos about
/proc/net/dev.

What i know for sure are the other informations. The duplex
settings did not change when the problem started.
The kernel and the peer (a switch) were always on 100mbit
fdx mode.

I'm using the 0.93 driver and hope that the problem will come
back so i can provide more information.
