  Log:
  Unify vlan_input() and vlan_input_tag():
  - For device drivers that support hardware vlan tag extraction, mbuf's
    M_VLANTAG is turned on and vlan tag is saved in mbuf.m_pkthdr.ether_vlantag
  - At the very beginning of ether_input_chain(), if the packet's ether type is
    vlan and hardware does not extract vlan tag, vlan_ether_decap() is called to
    do software vlan tag extraction.
  - Instead of BPF_MTAP(), ETHER_BPF_MTAP() is used in ether_input_chain() to
    deliver possible vlan tagging information to the bpf listeners.
  - Ether header is restored before calling vlan_input(), so under most cases,
    extra ether header copy is avoided.  vlan_input() does nothing more than
    finding vlan interface and looping back the packet to ether_input_chain()
    with vlan interface as input interface.
