Log:
  MFC r316716:
    Inherit IPv6 checksum offloading flags to vlan interfaces.
  
    if_vlan(4) interfaces inherit IPv4 checksum offloading flags from the
    parent when VLAN_HWCSUM and VLAN_HWTAGGING flags are present on the
    parent interface. Do the same for IPv6 checksum offloading flags.
