You probably have a duplex mismatch between your card and your hub/switch.

I don't quite see how this patch and the duplex mismatch play together, it
probably only hides the real problem.

Can you download mii-diag and run it with 'mii-diag -v' ?

My guess is that you somehow force duplex settings either on the card or
on the switch (if it's a switch) or the autonegotiation fails for some
reason.

If you don't specify details about your hub/switch and how is everything
configured, any comparison is meaningless.
