First thought - just a cross-over cable between two interfaces. Or

Crossover cables are only needed with 10 & 100 Mb.  Gigabit & 10G
use all 4 pairs in both directions.
The latter I knew, but it had not occurred to me that it would
eliminate the need for a cross-over cable. Thanks.



Even at 100 Mb, newer equipment can often automagically detect what's
at the other end.

Yes lots of switches do auto-switching, but I'm not sure if I've seen
network cards do it too.
