Re: [PATCH 11/16] ipv4: Cache input routes in fib_info nexthops.

	Hello,

	The problem with rt_iif is worse. May be we
can cache only the first iif, other packets will see
different iif in nh_rth_input and will get non-cached
result. For boxes with 2 or more interfaces only one
can use the cache. One setup can have large traffic
from LAN, other can be server for remote clients.

	May be we can replace rt_iif with skb->dev->ifindex ?
If we have dst, there must be skb->dev ? Only for
output routes we should check places that rely on
inet_iif().
