DPDK Release 24.03
==================

New Features
------------

* **Added HiSilicon UACCE bus support.**

  Added UACCE (Unified/User-space-access-intended Accelerator Framework) bus
  driver so that the accelerator devices such as a compress, crypto,
  DMA and ethernet devices could be seen and registered in DPDK.

* **Introduced argument parsing library.**

  The argparse library was added to help writing user-friendly applications,
  replacing ``getopt()`` usage.

* **Improved RSS hash algorithm support.**

  Added new function ``rte_eth_find_rss_algo``
  to get RSS hash algorithm by its name.

* **Added query of used descriptors number in Tx queue.**

  * Added a fast path function ``rte_eth_tx_queue_count``
    to get the number of used descriptors for a Tx queue.

* **Added hash calculation of an encapsulated packet as done by the HW.**

  Added function to calculate hash when doing tunnel encapsulation:
  ``rte_flow_calc_encap_hash()``

* **Added flow matching items and action.**

  * Added ``RTE_FLOW_ITEM_TYPE_COMPARE`` to allow matching
    on comparison result between packet fields or value.
  * Added ``RTE_FLOW_ITEM_TYPE_RANDOM`` to match a random value,
    and ``RTE_FLOW_FIELD_RANDOM`` to represent it with a field ID.
  * Added ``RTE_FLOW_ACTION_TYPE_NAT64`` to offload header conversion
    between IPv4 and IPv6.

* **Added flow template table resizing.**

  * ``RTE_FLOW_TABLE_SPECIALIZE_RESIZABLE_TABLE`` table configuration bit.
    Set at table creation to allow future resizing.
  * ``rte_flow_template_table_resizable()``.
    Query whether template table can be resized.
  * ``rte_flow_template_table_resize()``.
    Reconfigure template table for new flows capacity.
  * ``rte_flow_async_update_resized()``.
    Reconfigure flows for the updated table configuration.
  * ``rte_flow_template_table_resize_complete()``.
    Complete table resize.

* **Updated Amazon ena (Elastic Network Adapter) net driver.**

  * Removed the reporting of ``rx_overruns`` errors from xstats
    and instead updated ``imissed`` counter with its value.
  * Added support for sub-optimal configuration notifications from the device.
  * Added ``normal_llq_hdr`` devarg that enforces normal LLQ header policy.
  * Added support for LLQ header size recommendation from the device.
  * Allowed large LLQ with 1024 entries when the device supports enlarged memory BAR.
  * Added `control_poll_interval` devarg that configures the control-path to work in poll-mode.
  * Added support for binding ports to `uio_pci_generic` kernel module.

* **Updated Atomic Rules' Arkville driver.**

  * Added support for Atomic Rules' TK242 packet-capture family of devices
    with PCI IDs: ``0x1024, 0x1025, 0x1026``.

* **Updated Broadcom bnxt driver.**

  * Added support for 5760X device family.

* **Updated HiSilicon hns3 ethdev driver.**

  * Added new device supporting RDMA/DCB/ROH with PCI IDs: ``0xa227, 0xa22c``.

* **Updated Marvell cnxk net driver.**

  * Added support for port representors.
  * Added support for ``RTE_FLOW_ITEM_TYPE_PPPOES`` flow item.
  * Added support for ``RTE_FLOW_ACTION_TYPE_SAMPLE`` flow item.
  * Added support for Rx inject.
  * Added support for ``rte_eth_tx_queue_count()``.
  * Optimized SW external mbuf free for better performance and avoid SQ corruption.

* **Updated Marvell OCTEON EP driver.**

  * Optimized mbuf rearm sequence.
  * Updated Tx queue mbuf free thresholds from 128 to 256 for better performance.
  * Updated Rx queue mbuf refill routine to use mempool alloc and reorder it
    to avoid mbuf write commits.
  * Added option to control ISM memory accesses which gives better performance
    for lower packet sizes when enabled.
  * Added optimized SSE Rx routines.
  * Added optimized AVX2 Rx routines.
  * Added optimized NEON Rx routines.

Removed Items
-------------

* log: Removed the statically defined logtypes that were used internally by DPDK.
  All code should be using the dynamic logtypes (see ``RTE_LOG_REGISTER()``).
  The application reserved statically defined logtypes ``RTE_LOGTYPE_USER1..RTE_LOGTYPE_USER8``
  are still defined.

* acc101: Removed obsolete code for non productized HW variant.


API Changes
-----------

* eal: Removed ``typeof(type)`` from the expansion of ``RTE_DEFINE_PER_LCORE``
  and ``RTE_DECLARE_PER_LCORE`` macros aligning them with their intended design.
  If use with an expression is desired applications can adapt by supplying
  ``typeof(e)`` as an argument.

* eal: Improved ``RTE_BUILD_BUG_ON`` by using C11 ``static_assert``.
  Non-constant expressions are now rejected instead of being silently ignored.

* gso: ``rte_gso_segment`` now returns ``-ENOTSUP`` for unknown protocols.

* ethdev: Renamed structure ``rte_flow_action_modify_data`` to be
  ``rte_flow_field_data`` for more generic usage.


ABI Changes
-----------

* No ABI change that would break compatibility with 23.11.
