Subject: ppp: call skb_checksum_complete_unset in ppp_receive_frame

From: Tom Herbert <tom@herbertland.com>

[ Upstream commit 3dfb05340ec6676e6fc71a9ae87bbbe66d3c2998 ]

Call checksum_complete_unset in PPP receive to discard checksum-complete
value. PPP does not pull checksum for headers and also modifies packet
as in VJ compression.
