This fixes breakage to iproute2 build with recent kernel headers
caused by:
commit a263653ed7
Author: Pablo Neira Ayuso <pablo@netfilter.org>
Date: Wed Jun 17 10:28:27 2015 -0500
netfilter: don't pull include/linux/netfilter.h from netns headers
The issue is that definitions in linux/in.h overlap with those
in netinet/in.h. This patch solves this by introducing the same
mechanism as was used to solve the same problem with linux/in6.h
