Yay.  iflib_gen_mac() has already thought kind-of similar and just took 
the entire(?) FreeBSD space for doing the same.  That code should be 
merged as well.

Bhyve is using a good chunk from the FreeBSD allocation; see 
sys/net/ieee_oui.h also for allocation guidelines (if I don’t 
misremember).

The fact that it might need figuring out should not prevent us from 
doing it right .. the third time .. maybe .. this time?

epair(4) is yet another one of the cloned interfaces which does magic 
for the ethernet addresses, not sure what else.
