api: fix compatibility of linux/in.h with netinet/in.h
u This fixes breakage to iproute2 build with recent kernel headers caused by: commit a263653ed798216c0069922d7b5237ca49436007 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 Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>
