451 .. This section should contain removed items in this release. Sample format:
453 * Add a short 1-2 sentence description of the removed item
456 This section is a comment. Do not overwrite or remove it.
457 Also, make sure to start the actual text at the margin.
458 =======================================================
460 * eal: Removed the deprecated function ``rte_get_master_lcore()``
461 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
463 * eal: The old api arguments that were deprecated for
464 blacklist/whitelist are removed. Users must use the new
465 block/allow list arguments.
467 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
468 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
470 * ethdev: Removed the port mirroring API. A more fine-grain flow API
471 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
472 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
473 the functions ``rte_eth_mirror_rule_set`` and
474 ``rte_eth_mirror_rule_reset`` along with the associated macros
475 ``ETH_MIRROR_*`` are removed.
477 * ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
478 driver callback. It is replaced by the more complete function
479 ``rte_eth_rx_descriptor_status``.
481 * ethdev: Removed deprecated ``shared`` attribute of the
482 ``struct rte_flow_action_count``. Shared counters should be managed
483 using indirect actions API (``rte_flow_action_handle_create`` etc).
485 * i40e: Removed i40evf driver.
486 iavf already became the default VF driver for i40e devices,
487 so there is no need to maintain i40evf.
493 .. This section should contain API changes. Sample format:
495 * sample: Add a short 1-2 sentence description of the API change
496 which was announced in the previous releases and made in this release.
497 Start with a scope label like "ethdev:".
498 Use fixed width quotes for ``function_names`` or ``struct_names``.
501 This section is a comment. Do not overwrite or remove it.
502 Also, make sure to start the actual text at the margin.
503 =======================================================
505 * eal: The lcore state ``FINISHED`` is removed from
506 the ``enum rte_lcore_state_t``.
507 The lcore state ``WAIT`` is enough to represent the same state.
509 * eal: Made ``rte_intr_handle`` structure definition hidden.
511 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
512 removed. Its usages have been replaced by a new function
513 ``rte_kvargs_get_with_value()``.
515 * cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
516 Calls to ``cmdline_free()`` after it need to be deleted from applications.
518 * cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
520 * cmdline: Made ``rdline`` structure definition hidden. Functions are added
521 to dynamically allocate and free it, and to access user data in callbacks.
523 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
524 that objects from this pool will not be used for device IO (e.g. DMA).
526 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
527 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
529 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
530 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
532 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
533 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
535 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
536 will be removed in DPDK 22.11.
538 * mbuf: The mbuf offload flags ``PKT_*`` are renamed as ``RTE_MBUF_F_*``. A
539 compatibility layer will be kept until DPDK 22.11.
540 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
541 to ``src_addr`` and ``dst_addr``, respectively.
543 * net: Added ``version`` and ``ihl`` bit-fields to ``struct rte_ipv4_hdr``.
544 Existing ``version_ihl`` field is kept for backward compatibility.
546 * ethdev: Added items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` to
549 * ethdev: Deprecated items and actions ``PF``, ``VF``, ``PHY_PORT``, ``PORT_ID``.
550 Suggested items and actions ``PORT_REPRESENTOR``, ``REPRESENTED_PORT`` instead.
552 * ethdev: Deprecated the use of attributes ``ingress`` / ``egress`` combined
553 with ``transfer``. See items ``PORT_REPRESENTOR``, ``REPRESENTED_PORT``.
555 * ethdev: ``rte_flow_action_modify_data`` structure updated, immediate data
556 array is extended, data pointer field is explicitly added to union, the
557 action behavior is defined in more strict fashion and documentation updated.
558 The immediate value behavior has been changed, the entire immediate field
559 should be provided, and offset for immediate source bitfield is assigned
560 from destination one.
562 * vhost: ``rte_vdpa_register_device``, ``rte_vdpa_unregister_device``,
563 ``rte_vhost_host_notifier_ctrl`` and ``rte_vdpa_relay_vring_used`` vDPA
564 driver interface are marked as internal.
566 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
567 rte_cryptodev_is_valid_dev as it can be used by the application as
568 well as PMD to check whether the device is valid or not.
570 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
571 as it is for drivers only and should be private to DPDK, and not
572 installed for app use.
574 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
575 renamed to ``aux_flags`` to indicate warnings and other information from
576 the crypto/security operation. This field will be used to communicate
577 events such as soft expiry with IPsec in lookaside mode.
579 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
580 moved to the end of the structure and extended to ``uint32_t``.
582 * cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
583 field to support total buffer length to facilitate protocol offload case.
585 * cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
586 ``dest_sgl`` to support out of place processing.
588 * bbdev: Added device info related to data byte endianness processing.
590 * eventdev: Moved memory used by timer adapters to hugepage. This will prevent
591 TLB misses if any and aligns to memory structure of other subsystems.
593 * fib: Added the ``rib_ext_sz`` field to ``rte_fib_conf`` and ``rte_fib6_conf``
594 so that user can specify the size of the RIB extension inside the FIB.
596 * ip_frag: All macros updated to have ``RTE_IP_FRAG_`` prefix.
597 Obsolete macros are kept for compatibility.
598 DPDK components updated to use new names.
599 Experimental function ``rte_frag_table_del_expired_entries`` was renamed
600 to ``rte_ip_frag_table_del_expired_entries``
601 to comply with other public API naming convention.
607 .. This section should contain ABI changes. Sample format:
609 * sample: Add a short 1-2 sentence description of the ABI change
610 which was announced in the previous releases and made in this release.
611 Start with a scope label like "ethdev:".
612 Use fixed width quotes for ``function_names`` or ``struct_names``.
615 This section is a comment. Do not overwrite or remove it.
616 Also, make sure to start the actual text at the margin.
617 =======================================================
619 * ethdev: All enums & macros updated to have ``RTE_ETH`` prefix and structures
620 updated to have ``rte_eth`` prefix. DPDK components updated to use new names.
622 * ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
623 Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
624 to internal queue data as input parameter. While this change is transparent
625 to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
626 is used by public inline function ``rte_eth_rx_queue_count``.
628 * ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
629 private data structures. ``rte_eth_devices[]`` can't be accessed directly
630 by user any more. While it is an ABI breakage, this change is intended
631 to be transparent for both users (no changes in user app is required) and
632 PMD developers (no changes in PMD is required).
634 * vhost: rename ``struct vhost_device_ops`` to ``struct rte_vhost_device_ops``.
636 * cryptodev: Made ``rte_cryptodev``, ``rte_cryptodev_data`` private
637 structures internal to DPDK. ``rte_cryptodevs`` can't be accessed directly
638 by user any more. While it is an ABI breakage, this change is intended
639 to be transparent for both users (no changes in user app is required) and
640 PMD developers (no changes in PMD is required).
642 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
643 routines used by inline outbound and inline inbound security processing were
644 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
645 have much processing in PMD specific callbacks but just 64-bit set/get.
646 This avoids a per packet function pointer jump overhead for such PMDs.
648 * security: A new option ``iv_gen_disable`` was added in structure
649 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
650 so that application can provide its own IV and test known test vectors.
652 * security: A new option ``tunnel_hdr_verify`` was added in structure
653 ``rte_security_ipsec_sa_options`` to indicate whether outer header
654 verification need to be done as part of inbound IPsec processing.
656 * security: A new option ``udp_ports_verify`` was added in structure
657 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
658 verification need to be done as part of inbound IPsec processing.
660 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
661 replace ``esn_soft_limit`` in IPsec configuration structure
662 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
663 and hard expiry limits. Limits can be either in number of packets or bytes.
665 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
666 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
667 packet IPv4 header checksum and L4 checksum need to be offloaded to
670 * security: A new structure ``esn`` was added in structure
671 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
672 application to start from an arbitrary ESN value for debug and SA lifetime
673 enforcement purposes.
675 * security: A new structure ``udp`` was added in structure
676 ``rte_security_ipsec_xform`` to allow setting the source and destination ports
677 for UDP encapsulated IPsec traffic.
679 * bbdev: Added capability related to more comprehensive CRC options,
680 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
682 * eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
683 were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
686 * eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
687 by the fastpath inline functions. The structures ``rte_eventdev``,
688 ``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
689 accessed directly by user any more. This change is transparent to both
690 applications and PMDs.
692 * eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
694 * ip_frag: Increased default value for config parameter
695 ``RTE_LIBRTE_IP_FRAG_MAX_FRAG`` from ``4`` to ``8``.
696 This parameter controls maximum number of fragments per packet
697 in IP reassembly table. Increasing this value from ``4`` to ``8``
698 will allow to cover common case with jumbo packet size of ``9KB``
699 and fragments with default frame size ``(1500B)``.
