From 55f79cc0c02f9ce8f85e965e9679796f62b790f5 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Wed, 14 Mar 2007 21:05:03 -0300 Subject: [PATCH] [IPV6]: Reset the network header in ip6_nd_hdr ip6_nd_hdr is always called immediately after a alloc_skb + skb_reserve sequence, i.e. when skb->tail is equal to skb->data, making it correct to use skb_reset_network_header().
