Hi Ben,
I have two questions,
1. When is this patch going to be released ?
2. Do we have any documentation for building modules from patch?

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.
