From 1018b5c01636c7c6bda31a719bda34fc631db29a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 4 Mar 2011 21:35:25 -0800 Subject: [PATCH] ipv4: Set rt->rt_iif more sanely on output routes. rt->rt_iif is only ever inspected on input routes, for example DCCP uses this to populate a route lookup flow key when generating replies to another packet. Therefore, setting it to anything other than zero on output routes makes no sense. Signed-off-by: David S.
