From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jason Wang Subject: [PATCH net-next 1/3] net: core: let skb_partial_csum_set() set transport header Date: Wed, 27 Mar 2013 17:11:20 +0800 Message-ID: <1364375482-7439-1-git-send-email-jasowang@redhat.com> Cc: mst@redhat.com, Jason Wang , Eric Dumazet To: davem@davemloft.net, netdev@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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.
