[SRU][Xenial][PATCH 0/4] Fixes for LP:1593235

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1593235

== SRU Justification ==
ovs/gre,vxlan, geneve: interface deletion are not notified via netlink with
linux kernels >= 4.3.

The four commits that resolve this bug are in mainline as of v4.7-rc6.  The
commits are already in Yakkety/Zesty and are also not needed in releases prior
to Xenial.   

Commit 106da663ff required a minor backport.  However, the other three
commits are clean cherry picks.
