  Modified files:
    sys/net              if_vlan.c 
  Log:
  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.
