  Log:
  Move ethernet VLAN tags from mtags to its own mbuf packet header field
  m_pkthdr.ether_vlan.  The presence of the M_VLANTAG flag on the mbuf
  signifies the presence and validity of its content.
  
  Drivers that support hardware VLAN tag stripping fill in the received
  VLAN tag (containing both vlan and priority information) into the
  ether_vtag mbuf packet header field:
  
          m->m_pkthdr.ether_vtag = vlan_id;       /* ntohs()? */
          m->m_flags |= M_VLANTAG;
  
  to mark the packet m with the specified VLAN tag.
  
  On output the driver should check the mbuf for the M_VLANTAG flag to
  see if a VLAN tag is present and valid:
  
          if (m->m_flags & M_VLANTAG) {
                  ... = m->m_pkthdr.ether_vtag;   /* htons()? */
                  ... pass tag to hardware ...
          }
  
  VLAN tags are stored in host byte order.  Byte swapping may be necessary.
  
  (Note: This driver conversion was mechanic and did not add or remove any
  byte swapping in the drivers.)
  
  Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition.  No more tag
  memory allocation have to be done.
