I applied both patches to master.  You specified 1.7 in the subject
lines.  Does this mean that you generated them against 1.7 or that you
need them applied to branch-1.7?  If it's the latter, that you need
them in branch-1.7 because that's what you're planning to ship and
support, please consider adopting branch-1.9 instead because that's
what we're recommending to downstreams at the moment for that purpose.
Here's what I wrote about that a little while ago (originally at
http://openvswitch.org/pipermail/dev/2013-January/024488.html):

We had a brief internal discussion about this today.  We recommend
version 1.9 to anyone planning a release on the basis of what Open
vSwitch has available now or in the next few months.  We should be
releasing OVS 1.9 really soon (within a week or two, I hope).  I don't
know of anything we're working on in the 1.9 branch, so it probably
won't change further barring discovery of bugs (which could just as well
get discovered after release and end up in a 1.9.x release).  It would
be perfectly reasonable to prepare for a release on the basis of the
current branch-1.9.

What I really want to discourage (even though I doubt you are
considering it) is doing anything based on current master, because
there's been a lot of big changes in internal structure and I'm sure
more bugs will be discovered there before it's really ready.
----------------------------------------------------------------------

We usually apply only bug fixes to release branches.  Arguably these
patches fix some problems so let me know if you really want them on
branch-1.{7,8} and I'll apply them there.  I'd also happily apply them
to branch-1.9; just let me know.
