Hi Ben,
I tested with latest OVS 2.16, which has your fix, even after setting
inactivity_probe to 0, we are still seeing ovs retrying after every 5 sec.
Can you please help us with this ?
Here are the details -

I just pushed the fixes to the repo, so it'll be released as part of the
next regular OVS release.
Building from a patch isn't any different from building any other way.

We first set the controller on the bridge and then set inactivity probe for our
controller to 0 to disable new connection attempts by ovs. After this we start
our controller to serve request. But in the new version of OVS somehow we still
see inactivity probe kicking in after every 5s and trying to reconnect. This
issue is triggered when we are in the middle of handling a packet in our
controller (i.e. OFController) which is blocked for almost 40s.
