From 4fd551d7bed93af60af61c5a324b8f5dff37953a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 17 Jul 2012 14:39:44 -0700 Subject: ipv4: Kill rt->rt_oif Never actually used. It was being set on output routes to the original OIF specified in the flow key used for the lookup. Adjust the only user, ipmr_rt_fib_lookup(), for greater correctness of the flowi4_oif and flowi4_iif values, thanks to feedback from Julian Anastasov. Signed-off-by: David S.
