The thing is, and I may be mis-understanding the explanations so far, the 'reset' is to renegotiate the connection ... if that is the case, and both the switch and the interface are already locked at a speed (in my case, both are hard coded to "100baseTX full duplex", then what is there to re-negotiate? And, why does it appear that *only* the em driver/interface requires this? I run bge and fxp interfaces on this same network, against the same switch, all locked at the same speed, and only the em driver exhibits this problem ... in fact, its only the *newer* em driver that does, as I have one server on the network, using an em interface, that is running an older FreeBSD 4.x kernel, that performs the same as the bge/fxp (ie. perfectly) ---- Marc G.
