Such a scenerio is a bug.
Anything that pulls off a header should use a utility function such
as skb_p

VXLAN device can receive skb with checksum partial. But the checksum
offset could be in outer header which is pulled on receive. This results
in negative checksum offset for the skb. Such skb can cause the assert
failure in skb_checksum_help(). The patch fixes the bug by checking for
negative offse
