11 The text in the sections below explains how to update the release notes.
13 Use proper spelling, capitalization and punctuation in all sections.
15 Variable and config names should be quoted as fixed width text:
18 Build the docs and view the output file to ensure the changes are correct::

27 .. This section should contain new features added in this release.
30 * **Add a title in the past tense with a full stop.**
32 Add a short 1-2 sentence description in the past tense.
33 The description should be enough to allow someone scanning
34 the release notes to understand the new feature.
36 If the feature adds a lot of sub-features you can use a bullet list
39 * Added feature foo to do something.
40 * Enhanced feature bar to do something else.
42 Refer to the previous release notes for examples.
44 Suggested order in release notes items:
45 * Core libs (EAL, mempool, ring, mbuf, buses)
46 * Device abstraction libs and PMDs (ordered alphabetically by vendor name)
48 - cryptodev (lib, PMDs)
49 - eventdev (lib, PMDs)
52 * Apps, Examples, Tools (if significant)

56 =======================================================
58 * **Added auxiliary bus support.**
60 Auxiliary bus provides a way to split function into child-devices
61 representing sub-domains of functionality. Each auxiliary device
62 represents a part of its parent functionality.
64 * **Added XZ compressed firmware support.**
66 Using ``rte_firmware_read``, a driver can now handle XZ compressed firmware
67 in a transparent way, with EAL uncompressing using libarchive if this library
68 is available when building DPDK.
70 * **Updated Intel iavf driver.**
72 * Added Tx QoS VF queue TC mapping.
74 * **Updated Intel ice driver.**
76 * In AVX2 code, added the new RX and TX paths to use the HW offload
77 features. When the HW offload features are configured to be used, the
78 offload paths are chosen automatically. In parallel the support for HW
79 offload features was removed from the legacy AVX2 paths.
80 * Added Tx QoS TC bandwidth configuration in DCF.
82 * **Added support for Marvell CN10K SoC ethernet device.**
84 * Added net/cnxk driver which provides the support for the integrated ethernet
87 * **Added support for Marvell CNXK crypto driver.**
89 * Added cnxk crypto PMD which provides support for an integrated
90 crypto driver for CN9K and CN10K series of SOCs. Support for
91 symmetric crypto algorithms is added to both the PMDs.
92 * Added support for lookaside protocol (IPsec) offload in cn10k PMD.
93 * Added support for asymmetric crypto operations in cn9k and cn10k PMD.
95 * **Added Baseband PHY CNXK PMD.**
97 Added Baseband PHY PMD which allows to configure BPHY hardware block
98 comprising accelerators and DSPs specifically tailored for 5G/LTE inline
99 usecases. Configuration happens via standard rawdev enq/deq operations. See
100 the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.

124 Use fixed width quotes for ``function_names`` or ``struct_names``.

141 which was announced in the previous releases and made in this release.
