=======================

See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
API and ABI deprecation notices are to be posted here.


Deprecation Notices
-------------------

* The following fields have been deprecated in rte_eth_stats:
  ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
  tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff

* ABI changes is planned for the reta field in struct rte_eth_rss_reta_entry64
  which handles at most 256 entries (8 bits) while newer NICs support larger
  tables (512 entries).
  It should be integrated in release 2.3.

* ABI changes are planned for struct rte_eth_fdir_flow in order to support
  extend flow director's input set. The release 2.2 does not contain these ABI
  changes, but release 2.3 will, and no backwards compatibility is planned.

* The scheduler statistics structure will change to allow keeping track of
  RED actions.

* librte_pipeline: The prototype for the pipeline input port, output port
  and table action handlers will be updated:
  the pipeline parameter will be added, the packets mask parameter will be
  either removed (for input port action handler) or made input-only.

* ABI changes are planned in cmdline buffer size to allow the use of long
  commands (such as RETA update in testpmd).  This should impact
  CMDLINE_PARSE_RESULT_BUFSIZE, STR_TOKEN_SIZE and RDLINE_BUF_SIZE.
  It should be integrated in release 2.3.
