I still don't understand this. You cite the following:
* OpenFlow 1.4.0 p.110:
* A OFPMP_FLOW_MONITOR multipart reply can not cross a barrier
* handshake. The switch must always send the OFPMP_FLOW_MONITOR
* multipart reply for a given flow table change before the reply
* to a OFPT_BARRIER_REQUEST request that follows the request
* responsible for the flow table change.
but can you elaborate on your thought process here? After all, when
we're paused we're not sending any flow table changes at all.
