Hello, I did read this chapter quite carefully, however I have some additional questions.
Did you mean, that I should use experimenter property type to send extended statistics? Because it seems that best option would be to add for example e.g. OFPPSPT_ RFC2819 to ofp_port_stats_prop_type along with proper C structures. However this would change OpenFlow protocol, so I guess I can't do it. So in simple words: Should I implement it exactly how it is currently done for ofputil_append_ofp14_port_stats (OF1.4) which contains Port statistics + ofp_port_stats_prop_ethernet, and append RFC2819 statistics at the end using Experimenter property type? Thank you in advance.

Please see section 7.3.5.5, "Port Statistics", in OpenFlow 1.5. -------------------------------------------------------------- Intel Shannon Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 Business address: Dromore House, East Park, Shannon, Co.
