243 This section is a comment. Do not overwrite or remove it.
244 Also, make sure to start the actual text at the margin.
245 =======================================================
247 * eal: Removed the deprecated function ``rte_get_master_lcore()``
248 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
250 * eal: The old api arguments that were deprecated for
251 blacklist/whitelist are removed. Users must use the new
252 block/allow list arguments.
254 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
255 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
257 * ethdev: Removed the port mirroring API. A more fine-grain flow API
258 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
259 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
260 the functions ``rte_eth_mirror_rule_set`` and
261 ``rte_eth_mirror_rule_reset`` along with the associated macros
262 ``ETH_MIRROR_*`` are removed.
264 * ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
265 driver callback. It is replaced by the more complete function
266 ``rte_eth_rx_descriptor_status``.
268 * ethdev: Removed deprecated ``shared`` attribute of the
269 ``struct rte_flow_action_count``. Shared counters should be managed
270 using indirect actions API (``rte_flow_action_handle_create`` etc).
272 * i40e: Removed i40evf driver.
273 iavf already became the default VF driver for i40e devices,
274 so there is no need to maintain i40evf.
280 .. This section should contain API changes. Sample format:
282 * sample: Add a short 1-2 sentence description of the API change
283 which was announced in the previous releases and made in this release.
284 Start with a scope label like "ethdev:".
285 Use fixed width quotes for ``function_names`` or ``struct_names``.
288 This section is a comment. Do not overwrite or remove it.
289 Also, make sure to start the actual text at the margin.
290 =======================================================
292 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
293 removed. Its usages have been replaced by a new function
294 ``rte_kvargs_get_with_value()``.
296 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
297 that objects from this pool will not be used for device IO (e.g. DMA).
299 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
300 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
302 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
303 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
305 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
306 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
308 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
309 will be removed in DPDK 22.11.
311 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
312 to ``src_addr`` and ``dst_addr``, respectively.
314 * net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
315 Existing ``version_ihl`` field is kept for backward compatibility.
317 * ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
320 * ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
321 Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
323 * ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
324 with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
326 * ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
327 array is extended, data pointer field is explicitly added to union, the
328 action behavior is defined in more strict fashion and documentation updated.
329 The immediate value behavior has been changed, the entire immediate field
330 should be provided, and offset for immediate source bitfield is assigned
331 from destination one.
333 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
334 rte_cryptodev_is_valid_dev as it can be used by the application as
335 well as PMD to check whether the device is valid or not.
337 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
338 as it is for drivers only and should be private to DPDK, and not
339 installed for app use.
341 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
342 renamed to ``aux_flags`` to indicate warnings and other information from
343 the crypto/security operation. This field will be used to communicate
344 events such as soft expiry with IPsec in lookaside mode.
346 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
347 moved to the end of the structure and extended to ``uint32_t``.
349 * cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
350 field to support total buffer length to facilitate protocol offload case.
352 * cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
353 ``dest_sgl`` to support out of place processing.
355 * bbdev: Added device info related to data byte endianness processing.
361 .. This section should contain ABI changes. Sample format:
363 * sample: Add a short 1-2 sentence description of the ABI change
364 which was announced in the previous releases and made in this release.
365 Start with a scope label like "ethdev:".
366 Use fixed width quotes for ``function_names`` or ``struct_names``.
369 This section is a comment. Do not overwrite or remove it.
370 Also, make sure to start the actual text at the margin.
371 =======================================================
373 * ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
374 Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
375 to internal queue data as input parameter. While this change is transparent
376 to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
377 is used by public inline function ``rte_eth_rx_queue_count``.
379 * ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
380 private data structures. ``rte_eth_devices[]`` can't be accessed directly
381 by user any more. While it is an ABI breakage, this change is intended
382 to be transparent for both users (no changes in user app is required) and
383 PMD developers (no changes in PMD is required).
385 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
386 routines used by inline outbound and inline inbound security processing were
387 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
388 have much processing in PMD specific callbacks but just 64-bit set/get.
389 This avoids a per packet function pointer jump overhead for such PMDs.
391 * security: A new option ``iv_gen_disable`` was added in structure
392 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
393 so that application can provide its own IV and test known test vectors.
395 * security: A new option ``tunnel_hdr_verify`` was added in structure
396 ``rte_security_ipsec_sa_options`` to indicate whether outer header
397 verification need to be done as part of inbound IPsec processing.
399 * security: A new option ``udp_ports_verify`` was added in structure
400 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
401 verification need to be done as part of inbound IPsec processing.
403 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
404 replace ``esn_soft_limit`` in IPsec configuration structure
405 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
406 and hard expiry limits. Limits can be either in number of packets or bytes.
408 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
409 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
410 packet IPv4 header checksum and L4 checksum need to be offloaded to
413 * security: A new structure ``esn`` was added in structure
414 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
415 application to start from an arbitrary ESN value for debug and SA lifetime
416 enforcement purposes.
418 * security: A new structure ``udp`` was added in structure
419 ``rte_security_ipsec_xform`` to allow setting the source and destination ports
420 for UDP encapsulated IPsec traffic.
422 * bbdev: Added capability related to more comprehensive CRC options,
423 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
429 .. This section should contain new known issues in this release. Sample format:
431 * **Add title in present tense with full stop.**
433 Add a short 1-2 sentence description of the known issue
434 in the present tense. Add information on any known workarounds.

449 * <vendor> platform with <vendor> <type of devices> combinations
