Hi Rob, Thanks! I am assuming you are talking about the value to set for the port_no of ofp_port_stats_request. So, in include/openflow/openflow/openflow.h, it is mentioned that OFPP_NONE must be used to request statistics for all ports. I guess both OFPP_NONE and OFPP_ALL should do the same thing then.
