[tulip] ANA 6944A/TX RX errors

[Christian Birchinger]

Hello,

I'm using a ANA6944A/TX port card with the version 0.93
(11/7/2001) of the tulip driver.

After booting, sending and receiving works perfectly in both
directions. (raw meter shows around 10mb/s)

After some mins i'm getting lots of RX errors while receiving.
The transferspeed only recheas around 300kb/s then.
