274 .. This section should contain removed items in this release. Sample format:
276 * Add a short 1-2 sentence description of the removed item
279 This section is a comment. Do not overwrite or remove it.
280 Also, make sure to start the actual text at the margin.
281 =======================================================
283 * eal: Removed the deprecated function ``rte_get_master_lcore()``
284 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
286 * eal: The old api arguments that were deprecated for
287 blacklist/whitelist are removed. Users must use the new
288 block/allow list arguments.
290 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
291 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
293 * ethdev: Removed the port mirroring API. A more fine-grain flow API
294 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
295 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
296 the functions ``rte_eth_mirror_rule_set`` and
297 ``rte_eth_mirror_rule_reset`` along with the associated macros
298 ``ETH_MIRROR_*`` are removed.
300 * ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
301 driver callback. It is replaced by the more complete function
302 ``rte_eth_rx_descriptor_status``.
304 * ethdev: Removed deprecated ``shared`` attribute of the
305 ``struct rte_flow_action_count``. Shared counters should be managed
306 using indirect actions API (``rte_flow_action_handle_create`` etc).
308 * i40e: Removed i40evf driver.
309 iavf already became the default VF driver for i40e devices,
310 so there is no need to maintain i40evf.
316 .. This section should contain API changes. Sample format:
318 * sample: Add a short 1-2 sentence description of the API change
319 which was announced in the previous releases and made in this release.
320 Start with a scope label like "ethdev:".
321 Use fixed width quotes for ``function_names`` or ``struct_names``.
324 This section is a comment. Do not overwrite or remove it.
325 Also, make sure to start the actual text at the margin.
326 =======================================================
328 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
329 removed. Its usages have been replaced by a new function
330 ``rte_kvargs_get_with_value()``.
332 * cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
333 Calls to ``cmdline_free()`` after it need to be deleted from applications.
335 * cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
337 * cmdline: Made ``rdline`` structure definition hidden. Functions are added
338 to dynamically allocate and free it, and to access user data in callbacks.
340 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
341 that objects from this pool will not be used for device IO (e.g. DMA).
343 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
344 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
346 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
347 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
349 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
350 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
352 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
353 will be removed in DPDK 22.11.
355 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
356 to ``src_addr`` and ``dst_addr``, respectively.
358 * net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
359 Existing ``version_ihl`` field is kept for backward compatibility.
361 * ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
364 * ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
365 Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
367 * ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
368 with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
370 * ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
371 array is extended, data pointer field is explicitly added to union, the
372 action behavior is defined in more strict fashion and documentation updated.
373 The immediate value behavior has been changed, the entire immediate field
374 should be provided, and offset for immediate source bitfield is assigned
375 from destination one.
377 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
378 rte_cryptodev_is_valid_dev as it can be used by the application as
379 well as PMD to check whether the device is valid or not.
381 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
382 as it is for drivers only and should be private to DPDK, and not
383 installed for app use.
385 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
386 renamed to ``aux_flags`` to indicate warnings and other information from
387 the crypto/security operation. This field will be used to communicate
388 events such as soft expiry with IPsec in lookaside mode.
390 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
391 moved to the end of the structure and extended to ``uint32_t``.
393 * cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
394 field to support total buffer length to facilitate protocol offload case.
396 * cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
397 ``dest_sgl`` to support out of place processing.
399 * bbdev: Added device info related to data byte endianness processing.
401 * eventdev: Moved memory used by timer adapters to hugepage. This will prevent
402 TLB misses if any and aligns to memory structure of other subsystems.
408 .. This section should contain ABI changes. Sample format:
410 * sample: Add a short 1-2 sentence description of the ABI change
411 which was announced in the previous releases and made in this release.
412 Start with a scope label like "ethdev:".
413 Use fixed width quotes for ``function_names`` or ``struct_names``.
416 This section is a comment. Do not overwrite or remove it.
417 Also, make sure to start the actual text at the margin.
418 =======================================================
420 * ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
421 Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
422 to internal queue data as input parameter. While this change is transparent
423 to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
424 is used by public inline function ``rte_eth_rx_queue_count``.
426 * ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
427 private data structures. ``rte_eth_devices[]`` can't be accessed directly
428 by user any more. While it is an ABI breakage, this change is intended
429 to be transparent for both users (no changes in user app is required) and
430 PMD developers (no changes in PMD is required).
432 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
433 routines used by inline outbound and inline inbound security processing were
434 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
435 have much processing in PMD specific callbacks but just 64-bit set/get.
436 This avoids a per packet function pointer jump overhead for such PMDs.
438 * security: A new option ``iv_gen_disable`` was added in structure
439 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
440 so that application can provide its own IV and test known test vectors.
442 * security: A new option ``tunnel_hdr_verify`` was added in structure
443 ``rte_security_ipsec_sa_options`` to indicate whether outer header
444 verification need to be done as part of inbound IPsec processing.
446 * security: A new option ``udp_ports_verify`` was added in structure
447 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
448 verification need to be done as part of inbound IPsec processing.
450 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
451 replace ``esn_soft_limit`` in IPsec configuration structure
452 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
453 and hard expiry limits. Limits can be either in number of packets or bytes.
455 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
456 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
457 packet IPv4 header checksum and L4 checksum need to be offloaded to
460 * security: A new structure ``esn`` was added in structure
461 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
462 application to start from an arbitrary ESN value for debug and SA lifetime
463 enforcement purposes.
465 * security: A new structure ``udp`` was added in structure
466 ``rte_security_ipsec_xform`` to allow setting the source and destination ports
467 for UDP encapsulated IPsec traffic.
469 * bbdev: Added capability related to more comprehensive CRC options,
470 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
472 * eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
473 were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
476 * eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
477 by the fastpath inline functions. The structures ``rte_eventdev``,
478 ``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
479 accessed directly by user any more. This change is transparent to both
480 applications and PMDs.
482 * eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
488 .. This section should contain new known issues in this release. Sample format:
490 * **Add title in present tense with full stop.**
492 Add a short 1-2 sentence description of the known issue
493 in the present tense. Add information on any known workarounds.
