+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
