- From 279c6c7fa64f5763e6b9f05e7ab3840092e702e7 Mon Sep 17 00:00:00 2001

- Subject: [PATCH] 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>
