  Log:
  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.
