Local interface is set to FD, but I don't know about the switch on
the other end. Though the switch is capable of 100baseTx-FD, 100baseTx,
10baseT-FD and 10baseT, I'm advised not to use auto-negotiation because it
doesn't always works correctly between switch and NIC. Forcing the NIC to
HD should always work I'm told...which I have tried, but doesn't improve
performance.

I have no control over the switch this eepro10 is connected to, but if
auto-negotiation fails the switch uses HD.
