  MFC: if_msk.c 1.30, if_msk.c 1.31 to RELENG_6
    To overcome hardware checksum offload bug msk(4) used to compute
    TCP/UDP checksum in driver for short frames. For frames that requires
    hardware VLAN tag insertion, the checksum offload trick does not
    work due to changes of checksum offset in mbuf after the VLAN tag.
  
    Disable hardware checksum offload for VLAN interface to fix the bug.
