    sys/net              if_vlan.c 
  MFC 1.84 by yar:
    Test the new M_VLANTAG packet flag before calling
    m_tag_locate().  This adds little overhead of a simple
    bitwise operation in case hardware VLAN acceleration
    is on, yet saves the more expensive function call if
    the acceleration is off.
