netdev: Custom statistics.
- 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.
