Some may call it a hack, but you can actually get away with reusing
the same mac address across all interfaces of the same logical host.
So long as you have routing entries configured or STP it sometimes
simplifies things.

Some heavy iron used to always ship this way by default--I've seen it
on some IBM Power machines specifically, maybe others.

In any case, wireshark/tcpdump are your friend. Fire them up and let
the packets fly.
