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.
73 * Added FDIR and RSS for GTPoGRE, support filter based on GTPU TEID/QFI,
74 outer most L3 or inner most l3/l4.
76 * **Updated Intel ice driver.**
78 * In AVX2 code, added the new RX and TX paths to use the HW offload
79 features. When the HW offload features are configured to be used, the
80 offload paths are chosen automatically. In parallel the support for HW
81 offload features was removed from the legacy AVX2 paths.
82 * Added Tx QoS TC bandwidth configuration in DCF.
84 * **Added support for Marvell CN10K SoC ethernet device.**
86 * Added net/cnxk driver which provides the support for the integrated ethernet
89 * **Updated Mellanox mlx5 driver.**
91 * Added support for meter hierarchy.
92 * Added devargs options ``allow_duplicate_pattern``.
93 * Added matching on IPv4 Internet Header Length (IHL).
94 * Added support for matching on VXLAN header last 8-bits reserved field.
95 * Optimized multi-thread flow rule insertion rate.
97 * **Added Wangxun ngbe PMD.**
99 Added a new PMD driver for Wangxun 1 Gigabit Ethernet NICs.
100 See the :doc:`../nics/ngbe` for more details.
102 * **Added support for Marvell CNXK crypto driver.**
104 * Added cnxk crypto PMD which provides support for an integrated
105 crypto driver for CN9K and CN10K series of SOCs. Support for
106 symmetric crypto algorithms is added to both the PMDs.
107 * Added support for lookaside protocol (IPsec) offload in cn10k PMD.
108 * Added support for asymmetric crypto operations in cn9k and cn10k PMD.
110 * **Updated Marvell OCTEON TX crypto PMD.**
112 Added support for crypto adapter OP_FORWARD mode.
114 * **Added Baseband PHY CNXK PMD.**
116 Added Baseband PHY PMD which allows to configure BPHY hardware block
117 comprising accelerators and DSPs specifically tailored for 5G/LTE inline
118 usecases. Configuration happens via standard rawdev enq/deq operations. See
119 the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.
121 * **Added support for Marvell CN10K, CN9K, event Rx/Tx adapter.**
123 * Added Rx/Tx adapter support for event/cnxk when the ethernet device requested
126 * **Added cppc_cpufreq support to Power Management library.**
128 Added support for cppc_cpufreq driver which works on most arm64 platforms.
130 * **Added multi-queue support to Ethernet PMD Power Management**
132 The experimental PMD power management API now supports managing
133 multiple Ethernet Rx queues per lcore.

146 =======================================================
152 .. This section should contain API changes. Sample format:
154 * sample: Add a short 1-2 sentence description of the API change
155 which was announced in the previous releases and made in this release.
156 Start with a scope label like "ethdev:".
157 Use fixed width quotes for ``function_names`` or ``struct_names``.

161 Also, make sure to start the actual text at the margin.
162 =======================================================
164 * eal: ``rte_strscpy`` sets ``rte_errno`` to ``E2BIG`` in case of string
167 * eal: ``rte_power_monitor`` and the ``rte_power_monitor_cond`` struct changed
168 to use a callback mechanism.
170 * rte_power: The experimental PMD power management API is no longer considered
171 to be thread safe; all Rx queues affected by the API will now need to be
172 stopped before making any changes to the power management scheme.
178 .. This section should contain ABI changes. Sample format:
180 * sample: Add a short 1-2 sentence description of the ABI change
181 which was announced in the previous releases and made in this release.
