321 .. This section should contain removed items in this release. Sample format:
323 * Add a short 1-2 sentence description of the removed item
326 This section is a comment. Do not overwrite or remove it.
327 Also, make sure to start the actual text at the margin.
328 =======================================================
330 * eal: Removed the deprecated function ``rte_get_master_lcore()``
331 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
333 * eal: The old api arguments that were deprecated for
334 blacklist/whitelist are removed. Users must use the new
335 block/allow list arguments.
337 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
338 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
340 * ethdev: Removed the port mirroring API. A more fine-grain flow API
341 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
342 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
343 the functions ``rte_eth_mirror_rule_set`` and
344 ``rte_eth_mirror_rule_reset`` along with the associated macros
345 ``ETH_MIRROR_*`` are removed.
347 * ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
348 driver callback. It is replaced by the more complete function
349 ``rte_eth_rx_descriptor_status``.
351 * ethdev: Removed deprecated ``shared`` attribute of the
352 ``struct rte_flow_action_count``. Shared counters should be managed
353 using indirect actions API (``rte_flow_action_handle_create`` etc).
355 * i40e: Removed i40evf driver.
356 iavf already became the default VF driver for i40e devices,
357 so there is no need to maintain i40evf.
363 .. This section should contain API changes. Sample format:
365 * sample: Add a short 1-2 sentence description of the API change
366 which was announced in the previous releases and made in this release.
367 Start with a scope label like "ethdev:".
368 Use fixed width quotes for ``function_names`` or ``struct_names``.
371 This section is a comment. Do not overwrite or remove it.
372 Also, make sure to start the actual text at the margin.
373 =======================================================
375 * eal: The lcore state ``FINISHED`` is removed from
376 the ``enum rte_lcore_state_t``.
377 The lcore state ``WAIT`` is enough to represent the same state.
379 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
380 removed. Its usages have been replaced by a new function
381 ``rte_kvargs_get_with_value()``.
383 * cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
384 Calls to ``cmdline_free()`` after it need to be deleted from applications.
386 * cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
388 * cmdline: Made ``rdline`` structure definition hidden. Functions are added
389 to dynamically allocate and free it, and to access user data in callbacks.
391 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
392 that objects from this pool will not be used for device IO (e.g. DMA).
394 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
395 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
397 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
398 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
400 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
401 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
403 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
404 will be removed in DPDK 22.11.
406 * mbuf: The mbuf offload flags ``PKT_*`` are renamed as ``RTE_MBUF_F_*``. A
407 compatibility layer will be kept until DPDK 22.11.
408 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
409 to ``src_addr`` and ``dst_addr``, respectively.
411 * net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
412 Existing ``version_ihl`` field is kept for backward compatibility.
414 * ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
417 * ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
418 Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
420 * ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
421 with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
423 * ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
424 array is extended, data pointer field is explicitly added to union, the
425 action behavior is defined in more strict fashion and documentation updated.
426 The immediate value behavior has been changed, the entire immediate field
427 should be provided, and offset for immediate source bitfield is assigned
428 from destination one.
430 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
431 rte_cryptodev_is_valid_dev as it can be used by the application as
432 well as PMD to check whether the device is valid or not.
434 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
435 as it is for drivers only and should be private to DPDK, and not
436 installed for app use.
438 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
439 renamed to ``aux_flags`` to indicate warnings and other information from
440 the crypto/security operation. This field will be used to communicate
441 events such as soft expiry with IPsec in lookaside mode.
443 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
444 moved to the end of the structure and extended to ``uint32_t``.
446 * cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
447 field to support total buffer length to facilitate protocol offload case.
449 * cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
450 ``dest_sgl`` to support out of place processing.
452 * bbdev: Added device info related to data byte endianness processing.
454 * eventdev: Moved memory used by timer adapters to hugepage. This will prevent
455 TLB misses if any and aligns to memory structure of other subsystems.
461 .. This section should contain ABI changes. Sample format:
463 * sample: Add a short 1-2 sentence description of the ABI change
464 which was announced in the previous releases and made in this release.
465 Start with a scope label like "ethdev:".
466 Use fixed width quotes for ``function_names`` or ``struct_names``.
469 This section is a comment. Do not overwrite or remove it.
470 Also, make sure to start the actual text at the margin.
471 =======================================================
473 * ethdev: All enums & macros updated to have ``RTE_ETH`` prefix and structures
474 updated to have ``rte_eth`` prefix. DPDK components updated to use new names.
476 * ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
477 Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
478 to internal queue data as input parameter. While this change is transparent
479 to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
480 is used by public inline function ``rte_eth_rx_queue_count``.
482 * ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
483 private data structures. ``rte_eth_devices[]`` can't be accessed directly
484 by user any more. While it is an ABI breakage, this change is intended
485 to be transparent for both users (no changes in user app is required) and
486 PMD developers (no changes in PMD is required).
488 * cryptodev: Made ``rte_cryptodev``, ``rte_cryptodev_data`` private
489 structures internal to DPDK. ``rte_cryptodevs`` can't be accessed directly
490 by user any more. While it is an ABI breakage, this change is intended
491 to be transparent for both users (no changes in user app is required) and
492 PMD developers (no changes in PMD is required).
494 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
495 routines used by inline outbound and inline inbound security processing were
496 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
497 have much processing in PMD specific callbacks but just 64-bit set/get.
498 This avoids a per packet function pointer jump overhead for such PMDs.
500 * security: A new option ``iv_gen_disable`` was added in structure
501 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
502 so that application can provide its own IV and test known test vectors.
504 * security: A new option ``tunnel_hdr_verify`` was added in structure
505 ``rte_security_ipsec_sa_options`` to indicate whether outer header
506 verification need to be done as part of inbound IPsec processing.
508 * security: A new option ``udp_ports_verify`` was added in structure
509 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
510 verification need to be done as part of inbound IPsec processing.
512 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
513 replace ``esn_soft_limit`` in IPsec configuration structure
514 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
515 and hard expiry limits. Limits can be either in number of packets or bytes.
517 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
518 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
519 packet IPv4 header checksum and L4 checksum need to be offloaded to
522 * security: A new structure ``esn`` was added in structure
523 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
524 application to start from an arbitrary ESN value for debug and SA lifetime
525 enforcement purposes.
527 * security: A new structure ``udp`` was added in structure
528 ``rte_security_ipsec_xform`` to allow setting the source and destination ports
529 for UDP encapsulated IPsec traffic.
531 * bbdev: Added capability related to more comprehensive CRC options,
532 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
534 * eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
535 were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
538 * eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
539 by the fastpath inline functions. The structures ``rte_eventdev``,
540 ``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
541 accessed directly by user any more. This change is transparent to both
542 applications and PMDs.
544 * eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
550 .. This section should contain new known issues in this release. Sample format:
552 * **Add title in present tense with full stop.**
