Merge branch 'l3mdev-fix-ip-tunnel-case-after-recent-l3mdev-change'
David Ahern says:
====================
l3mdev: Fix ip tunnel case after recent l3mdev change
Second patch provides a fix for ip tunnels after the recent l3mdev change
that avoids touching the oif in the flow struct. First patch preemptively
provides a fix to an existing function that the second patch uses.
