Xen doesn't have anything to do with your card. it doesn't have any drivers,
nor manages it in any way. What you 'see' in DomU is an emulated card,
usually a RealTek 8139, or an Intel e1000, no matter what you physically have
on the machine.
this emulated card doesn't talk to hardware, so it could be any kind of card.
also, since it really doesn't manage a network wire, it can work at any
speed; no matter what does it say.
try to benchmark it. probably won't be a speed demon; but quite possibly
would get more than 100 Mb/sec
