I think this is Cisco gear, I'll check with our lab guy today. In the meantime I'll test my driver back to back with some other machines, I should find something that does pause eventually :-) It's handy when you have a gigabit MAC on a 400Mhz ARM9 to be able to throttle the peer despite all the other problems with Pause :-) Cheers, Ben.
