  Modified files:
    sys/net              if_vlan.c if_vlan_var.h 
  Log:
  o eliminate separate callback interface for h/w tagged input packets; instead
    drivers "tag packets" with an m_tag and the input packet handling recognizes
    such packets and does the right thing
  o track the number of active vlans on an interface; this lets lots of places
    only do vlan-specific processing when needed
  o track changes to ether_ifdetach/ether_ifattach
  o track bpf changes
  o eliminate the use of M_PROTO1 for communicating to drivers about tagged
    packets
  o eliminate the use of IFF_LINK0 for drivers communicating to the vlan code
    that they support h/w tagging; replaced by explicit interface capabilities
  o add ifnet capabilities for h/w tagging and support of "large mtu's"
  o use new interface capabilities to auto-configure use of large mtu's and h/w
    tagging
  o add support for proper handling of promiscuous mode
  o document driver/vlan communication conventions
