  Added files:
    sys/net/vlan         if_vlan_ether.c 
  Log:
  - Embed ether vlan tag in mbuf packet header.  Add an mbuf flag to mark that
    this field is valid.
  - Hide ifvlan after the above change; drivers support hardware vlan tagging
    only need to check ether_vlantag in mbuf packet header.
  - Convert all drivers that support hardware vlan tagging to use vlan tag field
    in mbug packet header.
  
  Obtained-from: FreeBSD
  
  Change the vlan/parent serializer releasing/holding sequences into mbuf
  dispatching.  There are several reasons to do so:
  - Avoid excessive vlan interface serializer releasing/holding
  - Touching parent interface if_snd without holding parent's serializer is
    unsafe
  - vlan's parent may disappear or be changed after vlan's serializer is released
  
  # This dispatching could be further optimized by packing all mbufs into one
  # netmsg using m_nextpkt to:
  # - Amortize netmsg sending cost
  # - Reduce the time that parent interface spends on serializer releasing/holding
