From cfe1fc7759fdacb0c650b575daed1692bf3eaece Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 16 Mar 2007 17:26:39 -0300 Subject: [SK_BUFF]: Introduce skb_network_header_len For the common sequence "skb->h.raw - skb->nh.raw", similar to skb->mac_len, that is precalculated tho, don't think we need to bloat skb with one more member, so just use this new helper, reducing the number of non-skbuff.h references to the layer headers even more.
