Summary

A vlan interface on top of a bridge will act as a layer 3 port for
bridge traffic on that vlan, sometimes called an "SVI". This allows
the host to send/receive traffic on that vlan without having to create
a separate epair(4) and vlan(4) to tag and untag the traffic.

sys/net/if_bridge.c
428	I think if_vlan_var.h is an appropriate spot for that. It already has vlan_trunkdev_p anyway. if_ethersubr.c already includes it, so we're not going to be causing any include pollution.
2484	vlan = DOT1Q_VID_NULL ?
