From e5d5decaedf41f5b03e6819789cc3ba8744d9f54 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Tue, 26 Mar 2013 23:11:20 +0000 Subject: [PATCH] net: core: let skb_partial_csum_set() set transport header For untrusted packets with partial checksum, we need to set the transport header for precise packet length estimation. We can just let skb_pratial_csum_set() to do this to avoid extra call to skb_flow_dissect() and simplify the caller.
