  The bridging output function puts the mbuf directly on the interfaces send
  queue so the output network card must support the same tagging mechanism as
  how the frame was input (prepended Ethernet header tag or stripped HW mflag).
  Now the vlan Ethernet header is _always_ stripped in ether_input and the mbuf
  flagged, only only network cards with VLAN_HWTAGGING enabled would properly
  re-tag any outgoing vlan frames.
  If the outgoing interface does not support hardware tagging then readd the vlan
  header to the front of the frame. Move the common vlan encapsulation in to
