ipv6: Paritially checksum full MTU frames
IPv6 will mark data that is smaller that mtu - headersize as CHECKSUM_PARTIAL, but if the data will completely fill the mtu, the packet checksum will be computed in software instead. Extend the conditional to include the data that fills the mtu as well. Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
