I am not an expert in tulip drivers but according to my recent experience
with it, this does not seem to be a driver problem. It is either:

1) cabling problem (try replacing the patch cable, check another wall
2) switch problem (e.g. one port in the swich sends half of the packets
to its /dev/null, had this experience with even an expensive cisco
switch), try another port in the switch or test with another switch;
3) hardware problem with the card (least likely), try another SMC1255TX.

Hope this helps.
