[Sorry for all the clutter tonight.]
I found a way to make the fxp timeouts happen on Intel boxes too.
This is a full duplex point-point link. (no hubs or switches) (The
machines are right next to eachother. It's just a short crossover
I'm trying to fill up both directions on that link. I'm getting
a total of ~190 megabits.

Nothing on the other end. That's slightly surprising. The test
