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. Miller <davem@davemloft.net>
