I think the problem is either with the cables or with the switch (or switch port configuration). I'm not very confident about the de and tx drivers, but as the author of the fxp driver, I'm very confident that there isn't anything wrong with that. The first thing to do would be to isolate the problem down to the side of the switch that is causing problems - either the 10Mbps side or the 100Mbps uplink side. The problem you're describing sounds like an error in autonegotiation or otherwise incorrectly configured duplex. I'm not familiar with the SMC switch, but if you can't get it to autonegotiate correctly, then I'd try manually setting all of the ports to half duplex (including the FreeBSD interface). Perhaps the 100Mbps uplink port is configured for full duplex? If so, that would be a problem since it's connected to a hub which is inherently half duplex. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
