No, the problem goes away if I do this, although then I hae the performance problems as before. I also noticed that even when the call to set_half_duplex is left in, the switch reports that the link is still in full duplex, 100Mb mode. I tried forcing half duplex on the switch but this didn't help. It actually looks like half duplex is not really being set correctly.
I plugged in a desktop with an eepro100 based card and forced the duplex to half with the command line options and the switch properly reported a half-duplex link had been negotiated, with the xircom card the switch reports full-duplex with or without the set_half_duplex line, which certainly implies it's not really working right.
Hope the helps. I won't be back at the office until Monday so that's the earliest I'll be able to test again, but I'll be glad to test any combination that I can.
Later, Tom
