That's supposed to be the policy; However, depending on the patch
sometimes openvswitch isn't even the main target of the change, so the
contributor may not be aware they should do so. There may be added
difficulty if the previous contributor didn't do their backport. I
think that lately there hasn't been particularly close co-ordination
between the trees, but ideally I think that as we approach an OVS
release, we would try to sync them up.

Kicking off a build on my local tester, I can at least report back on
that. I see you've tested on a few platforms as well, that's great. If
you were able to add even one or two basic tests to the
system-kmod-testsuite for the new L3 bits (eg, set up a tunnel and
send some packets through it), that would sure go some way towards
knowing that this series does what it intends without bad
side-effects, and also would help us to catch any potential
regressions.

Sure thing, userspace can be decoupled.
