[SRU][Xenial][PATCH 0/2] Fixes for LP:1744078

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1744078

== SRU Justification ==
On kernel versions < 4.8: x-netns vti is broken due to this bug.  This is resolved by the following commit:
11d7a0bb95ea ("xfrm: Only add l3mdev oif to dst lookups")     

This is a regression introduced by: commit 42a7b32b73d6 ("xfrm: Add oif to dst lookups")

Commit 1a8524794fc is also required as a prereq to fix build errors after picking
commit 11d7a0bb95ea into Xenial.

Commit 11d7a0bb95ea is in mainline as of v4.8-rc7.  It was also cc'd to upstream
stable, but it never landed in upstream 4.4.y as of yet.

== Fixes ==
1a8524794fc "(net: l3mdev: Add master device lookup by index)"
11d7a0bb95e "(xfrm: Only add l3mdev oif to dst lookups)"

== Regression Potential ==
Low.  These patches are required to fix an existing regression.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
