From f8f626754ebeca613cf1af2e6f890cfde0e74d5b Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Fri, 9 Nov 2012 17:05:07 -0800 Subject: ipv6: Move ipv6_find_hdr() out of Netfilter code. Open vSwitch will soon also use ipv6_find_hdr() so this moves it out of Netfilter-specific code into a more common location.
