From d56f90a7c96da5187f0cdf07ee7434fe6aa78bbc Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 10 Apr 2007 20:50:43 -0700 Subject: [SK_BUFF]: Introduce skb_network_header() For the places where we need a pointer to the network header, it is still legal to touch skb->nh.raw directly if just adding to, subtracting from or setting it to another layer header.
