easier to add new buses later.
-* The xstats API and rte_eth_xstats struct will be changed to allow retrieval
- of values without any string copies or parsing.
- No backwards compatibility is planned, as it would require code duplication
- in every PMD that supports xstats.
-
* ABI changes are planned for adding four new flow types. This impacts
RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
but release 2.3 will. [postponed]
