The errors I received were the classic errors which denote that there is a
negotiation mismatch between the card and the switch. I had the card set to
auto-negotiate (the default for the fxp driver); the switch was hard-set to
full-duplex 100Mb. The errors were "FCE" errors, and the symptom was
rediculously poor performance (20KB/sec). Once I set both card and switch
port to full-duplex 100Mb, the errors disappeared and I was able to get
"normal" performance (which for me is around 5-6MB/sec. average).
