I just read some articles about macvlan. It looks like a simplified bridge setup without showing the bridge details to the user.

The use of if_bridge + if_epair is a common way to create such a setup in FreeBSD.
NB: if_bridge + if_epair != ng_eiface + ng_bridge although functionality might look similar.

NB2: What are you trying to accomplish?
