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. /bz
