Re: [PATCH net] net: Handle negative checksum offset in skb-checksum-help

VXLAN device can receive skb with checksum partial. But the checksum
offset could be in outer header which is pulled on receive.

Such a scenerio is a bug.

Anything that pulls off a header should use a utility function such
as skb_pull_rcsum() or skb_postpull_rcsum() to make sure this gets
fixed up properly.
