Vxlan was trying to use postpull_rcsum to allow receive checksum offload to work on drivers using CHECKSUM_COMPLETE method. But this doesn't work correctly. Just force full receive checksum on received packet. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
