From d75a02c13d11c166a171e4e08a42da94506cf53c Mon Sep 17 00:00:00 2001
From: Luotao Fu <l.fu@pengutronix.de>
Date: Fri, 11 Dec 2009 16:07:08 +0100
Subject: [PATCH] remove dependency on kernel header include

make a local copy of the can/netlink.h. This way we don't have to include a
kernel include directory to build any more.
