Just a minor note: GigE should not require a crossover cable.  It's
supposed to work to connect two GigE adapters with a straight-thru
cable.  I verified this with two Intel em NICs, quite a while ago.
As I recall, when I used a crossover cable, I could not get the
adapters to go to 1000, only 100.  That might have been the cable,
or not.
