- New get_custom_stats interface function is added to netdev. It allows particular netdev implementation to expose custom counters in dictionary format (counter name/counter value). - New statistics are retrieved using experimenter code and are printed as a result to ofctl dump-ports. - New counters are available for OpenFlow 1.4+. - New statistics are printed to output via ofctl only if those are present in reply message. - New statistics definition is added to include/openflow/intel-ext.h. - Custom statistics are implemented only for dpdk-physical port type. - DPDK-physical implementation uses xstats to collect statistics. Only dropped and error counters are exposed.
