    1111 * A good way to track packets and transactions between datapath and controller is via buffer Id for switch-initiated conversations, and by XID for controller-initiated transactions. A caveat is that the buffer ID is only applicable to a subset of messages e.g. !PacketIns and !PacketOuts. A -1 buffer ID indicates a controller-generated packet (e.g. by a flow pushing tool or via a REST API for static flows).

     13 * making !FlowMods. If not building a match object from a !PacketIn, make sure to not forget to invert the wildcard bit for the field you are setting. The default match is wildcarded to all.
