| 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. |
