432 .. This section should contain removed items in this release. Sample format:
434 * Add a short 1-2 sentence description of the removed item
437 This section is a comment. Do not overwrite or remove it.
438 Also, make sure to start the actual text at the margin.
439 =======================================================
441 * eal: Removed the deprecated function ``rte_get_master_lcore()``
442 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
444 * eal: The old api arguments that were deprecated for
445 blacklist/whitelist are removed. Users must use the new
446 block/allow list arguments.
448 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
449 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
451 * ethdev: Removed the port mirroring API. A more fine-grain flow API
452 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
453 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
454 the functions ``rte_eth_mirror_rule_set`` and
455 ``rte_eth_mirror_rule_reset`` along with the associated macros
456 ``ETH_MIRROR_*`` are removed.
458 * ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
459 driver callback. It is replaced by the more complete function
460 ``rte_eth_rx_descriptor_status``.
462 * ethdev: Removed deprecated ``shared`` attribute of the
463 ``struct rte_flow_action_count``. Shared counters should be managed
464 using indirect actions API (``rte_flow_action_handle_create`` etc).
466 * i40e: Removed i40evf driver.
467 iavf already became the default VF driver for i40e devices,
468 so there is no need to maintain i40evf.
474 .. This section should contain API changes. Sample format:
476 * sample: Add a short 1-2 sentence description of the API change
477 which was announced in the previous releases and made in this release.
478 Start with a scope label like "ethdev:".

482 This section is a comment. Do not overwrite or remove it.
483 Also, make sure to start the actual text at the margin.
484 =======================================================
486 * eal: The lcore state ``FINISHED`` is removed from
487 the ``enum rte_lcore_state_t``.
488 The lcore state ``WAIT`` is enough to represent the same state.
490 * eal: Made ``rte_intr_handle`` structure definition hidden.
492 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
493 removed. Its usages have been replaced by a new function
494 ``rte_kvargs_get_with_value()``.
496 * cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
497 Calls to ``cmdline_free()`` after it need to be deleted from applications.
499 * cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
501 * cmdline: Made ``rdline`` structure definition hidden. Functions are added
502 to dynamically allocate and free it, and to access user data in callbacks.
504 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
505 that objects from this pool will not be used for device IO (e.g. DMA).
507 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
508 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
510 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
511 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
513 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
514 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
516 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
517 will be removed in DPDK 22.11.
519 * mbuf: The mbuf offload flags ``PKT_*`` are renamed as ``RTE_MBUF_F_*``. A
520 compatibility layer will be kept until DPDK 22.11.
521 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
522 to ``src_addr`` and ``dst_addr``, respectively.
524 * net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
525 Existing ``version_ihl`` field is kept for backward compatibility.
527 * ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
530 * ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
531 Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
533 * ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
534 with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
536 * ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
537 array is extended, data pointer field is explicitly added to union, the
538 action behavior is defined in more strict fashion and documentation updated.
539 The immediate value behavior has been changed, the entire immediate field
540 should be provided, and offset for immediate source bitfield is assigned
541 from destination one.
543 * vhost: ``rte_vdpa_register_device``, ``rte_vdpa_unregister_device``,
544 ``rte_vhost_host_notifier_ctrl`` and ``rte_vdpa_relay_vring_used`` vDPA
545 driver interface are marked as internal.
547 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
548 rte_cryptodev_is_valid_dev as it can be used by the application as
549 well as PMD to check whether the device is valid or not.
551 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
552 as it is for drivers only and should be private to DPDK, and not
553 installed for app use.
555 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
556 renamed to ``aux_flags`` to indicate warnings and other information from
557 the crypto/security operation. This field will be used to communicate
558 events such as soft expiry with IPsec in lookaside mode.
560 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
561 moved to the end of the structure and extended to ``uint32_t``.
563 * cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
564 field to support total buffer length to facilitate protocol offload case.
566 * cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
567 ``dest_sgl`` to support out of place processing.
569 * bbdev: Added device info related to data byte endianness processing.
571 * eventdev: Moved memory used by timer adapters to hugepage. This will prevent
572 TLB misses if any and aligns to memory structure of other subsystems.
574 * fib: Added the ``rib_ext_sz`` field to ``rte_fib_conf`` and ``rte_fib6_conf``
575 so that user can specify the size of the RIB extension inside the FIB.
581 .. This section should contain ABI changes. Sample format:
583 * sample: Add a short 1-2 sentence description of the ABI change
584 which was announced in the previous releases and made in this release.
585 Start with a scope label like "ethdev:".
586 Use fixed width quotes for ``function_names`` or ``struct_names``.
589 This section is a comment. Do not overwrite or remove it.
590 Also, make sure to start the actual text at the margin.
591 =======================================================
593 * ethdev: All enums & macros updated to have ``RTE_ETH`` prefix and structures
594 updated to have ``rte_eth`` prefix. DPDK components updated to use new names.
596 * ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
597 Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
598 to internal queue data as input parameter. While this change is transparent
599 to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
600 is used by public inline function ``rte_eth_rx_queue_count``.
602 * ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
603 private data structures. ``rte_eth_devices[]`` can't be accessed directly
604 by user any more. While it is an ABI breakage, this change is intended
605 to be transparent for both users (no changes in user app is required) and
606 PMD developers (no changes in PMD is required).
608 * vhost: rename ``struct vhost_device_ops`` to ``struct rte_vhost_device_ops``.
610 * cryptodev: Made ``rte_cryptodev``, ``rte_cryptodev_data`` private
611 structures internal to DPDK. ``rte_cryptodevs`` can't be accessed directly
612 by user any more. While it is an ABI breakage, this change is intended
613 to be transparent for both users (no changes in user app is required) and
614 PMD developers (no changes in PMD is required).
616 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
617 routines used by inline outbound and inline inbound security processing were
618 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
619 have much processing in PMD specific callbacks but just 64-bit set/get.
620 This avoids a per packet function pointer jump overhead for such PMDs.
622 * security: A new option ``iv_gen_disable`` was added in structure
623 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
624 so that application can provide its own IV and test known test vectors.
626 * security: A new option ``tunnel_hdr_verify`` was added in structure
627 ``rte_security_ipsec_sa_options`` to indicate whether outer header
628 verification need to be done as part of inbound IPsec processing.
630 * security: A new option ``udp_ports_verify`` was added in structure
631 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
632 verification need to be done as part of inbound IPsec processing.
634 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
635 replace ``esn_soft_limit`` in IPsec configuration structure
636 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
637 and hard expiry limits. Limits can be either in number of packets or bytes.
639 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
640 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
641 packet IPv4 header checksum and L4 checksum need to be offloaded to
644 * security: A new structure ``esn`` was added in structure
645 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
646 application to start from an arbitrary ESN value for debug and SA lifetime
647 enforcement purposes.
649 * security: A new structure ``udp`` was added in structure
650 ``rte_security_ipsec_xform`` to allow setting the source and destination ports
651 for UDP encapsulated IPsec traffic.
653 * bbdev: Added capability related to more comprehensive CRC options,
654 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
656 * eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
657 were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
660 * eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
661 by the fastpath inline functions. The structures ``rte_eventdev``,
662 ``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
663 accessed directly by user any more. This change is transparent to both
664 applications and PMDs.
666 * eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
668 * ip_frag: Increased default value for config parameter
669 ``RTE_LIBRTE_IP_FRAG_MAX_FRAG`` from ``4`` to ``8``.
670 This parameter controls maximum number of fragments per packet
671 in IP reassembly table. Increasing this value from ``4`` to ``8``
672 will allow to cover common case with jumbo packet size of ``9KB``
673 and fragments with default frame size ``(1500B)``.
