  Log:
  Allocate the M_VLANTAG m_pkthdr flag, and use it to indicate that
  a packet has VLAN mbuf tag attached.  This is faster to check than
  m_tag_locate(), and allows us to use the tags in non-vlan(4) VLAN
  producers.
  
  The first argument to VLAN_OUTPUT_TAG() is now unused but retained
  for backward compatibility.
  
  While here, embellish a fix in rev. 1.174 of if_ethersubr.c -- it
  now checks for packets with VLAN (mbuf) tags, and it should now
  be possible to bridge(4) on vlan(4)'s whose parent interfaces
  support VLAN decapsulation in hardware.
