It looks like a simplified bridge setup without showing the bridge details to the user. https://i1.wp.com/ipwithease.com/wp-content/uploads/2021/09/MACVLAN-DP.jpg 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? Regards, Ronald.
