I would double check that you tested 2.4.1 because it looks like the
fix should already be part of that release. (You also said that you
used 2.3.3 but based on the directory name it was actually 2.3.1). No
version of 2.3 has the fix for this issue but I applied the patch to
that branch in the event that we end up doing another release off of
it.

In any event, I would recommend using OVS 2.5 as that is the current
long term stable release.
