From 9c70220b73908f64792422a2c39c593c4792f2c5 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 25 Apr 2007 18:04:18 -0700 Subject: [SK_BUFF]: Introduce skb_transport_header(skb) For the places where we need a pointer to the transport header, it is still legal to touch skb->h.raw directly if just adding to, subtracting from or setting it to another layer header.
