Hi, I'm sorry I mistook.
The statistics of OFPP_CONTROLLER does not seems to be maintained by the switch. I mistook the statistics of OFPP_LOCAL for that of OFPP_CONTROLLER. The OFPP_CONTROLLER ports seem to communicate on the NON ofport, the controller to switch connections are established through the normal IP interfaces. So, for monitoring the control packet loss, we can only monitor the statistics of the interface to the controller (e.g. eth0, eth1) at the switch, I guess...
