| 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>
 | |

 | |
| 
 | |
|    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
