[ovs-discuss] Flow insertion no overwrite

Is there a way to insert a flow without overwriting with OFPFlowMod? So if
a flow exists do nothing but if the flow is missing add a new one.
Currently I'm querying all active flows with EventOFPFlowStatsReply and
then comparing active flows and inserting depending on that, but that seems
inefficient and I'm wondering If I'm missing a simple solution.

Thank you,
