crypto PMD lookaside protocol offload for IPsec.
* **Added mlx5 compress PMD.**
Added a new compress PMD driver for Bluefield 2 adapters.
See the :doc:`../compressdevs/mlx5` for more details.
* **Added python script to run crypto perf tests and graph the results.**
A new python script has been added to automate running crypto performance
tests and output graphed results to PDF files.
See the :doc:`../tools/cryptoperf` guide for more details.
* **Added Windows support to pmdinfogen.**
PMD information strings were added for Windows as well as for other OS.
Extracting them from Windows DLL is not yet supported.
The build-time tool pmdinfogen was rewritten in Python,
thus libelf dependency was replaced with pyelftools as new build dependency.
* **Added support for build-time checking of header includes.**
A new build option ``check_includes`` has been added, which, when enabled,
will perform build-time checking on DPDK public header files, to ensure none
are missing dependent header includes. This feature, disabled by default, is
intended for use by developers contributing to the DPDK SDK itself, and is
integrated into the build scripts and automated CI for patch contributions.
Removed Items
-------------
.. This section should contain removed items in this release. Sample format:
* Add a short 1-2 sentence description of the removed item
in the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* The internal header files ``rte_ethdev_driver.h``, ``rte_ethdev_vdev.h`` and
``rte_ethdev_pci.h`` are no longer installed as part of the DPDK
``ninja install`` action and are renamed to ``ethdev_driver.h``,
``ethdev_vdev.h`` and ``ethdev_pci.h`` respectively in the source tree, to
reflect the fact that they are non-public headers.
* The internal header files ``rte_eventdev_pmd.h``, ``rte_eventdev_pmd_vdev.h``
and ``rte_eventdev_pmd_pci.h`` are no longer installed as part of the DPDK
``ninja install`` action and are renamed to ``eventdev_pmd.h``,
``eventdev_pmd_vdev.h`` and ``eventdev_pmd_pci.h`` respectively in the source
tree, to reflect the fact that they are non-public headers.
* Removed support for NetXtreme devices belonging to ``BCM573xx and
BCM5740x`` families. Specifically the support for the following Broadcom
PCI device IDs ``0x16c8, 0x16c9, 0x16ca, 0x16ce, 0x16cf, 0x16df, 0x16d0,``
``0x16d1, 0x16d2, 0x16d4, 0x16d5, 0x16e7, 0x16e8, 0x16e9`` has been removed.
* The ``check-includes.sh`` script for checking DPDK header files has been
removed, being replaced by the ``check_includes`` build option described
above.
API Changes
-----------
.. This section should contain API changes. Sample format:
* sample: Add a short 1-2 sentence description of the API change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* config: Removed the old macros, included in ``rte_config.h``,
to indicate which DPDK libraries and drivers are built.
The new macros are generated by meson in a standardized format:
``RTE_LIB_<NAME>`` and ``RTE_<CLASS>_<NAME>``, where ``NAME`` is
the upper-case component name, e.g. ``EAL``, ``ETHDEV``, ``VIRTIO``,
and ``CLASS`` is the upper-case driver class, e.g. ``NET``, ``CRYPTO``.
* cryptodev: The structure ``rte_cryptodev`` has been updated with pointers
for adding enqueue and dequeue callbacks.
ABI Changes
-----------
.. This section should contain ABI changes. Sample format:
* sample: Add a short 1-2 sentence description of the ABI change
which was announced in the previous releases and made in this release.
Start with a scope label like "ethdev:".
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* No ABI change that would break compatibility with 20.11.
* The experimental function ``rte_telemetry_init`` has been removed from the
public API and is now an internal-only function. Where telemetry library is
available, it is called automatically from ``rte_eal_init()`` and so no end
application need use it.
Known Issues
------------
