Same problem here with the xl0 driver. My 3Com 3c905C-TX Fast Etherlink XL connects to a Cisco Micro Switch (1548, unmanaged). According to the lights on the back of the switch everything runs at 100 Mbits full-duplex initially (that is after a reboot). However after a while the switch indicates that it is running at 100 Mbits half-duplex. I don't know what causes it, but this is happening for at least a month. When this happens 'ifconfig -a' will still report that everything is running at 100 Mbits full-duplex. Judging from the performance and what the Cisco switch indicates this is not true, it is running half-duplex! Unfortunately the switch is unmanaged hence I am not able to explicitely set the switch to 100 Mbits full-duplex. Using ifconfig to set the nic to 10baseT/UTP and then back to 100baseTX full-duplex doesn't help. Only a reboot will bring the NIC back to 100 Mbits full duplex mode. -- Guido
