The description should be enough to allow someone scanning the release notes to understand the new feature. If the feature adds a lot of sub-features you can use a bullet list like this: * Added feature foo to do something. * Enhanced feature bar to do something else. Refer to the previous release notes for examples. Suggested order in release notes items: * Core libs (EAL, mempool, ring, mbuf, buses) * Device abstraction libs and PMDs - ethdev (lib, PMDs) - cryptodev (lib, PMDs) - eventdev (lib, PMDs) - etc * Other libs * Apps, Examples, Tools (if significant) This section is a comment.

Another new function ``rte_eth_burst_mode_option_name`` is provided for burst mode options stringification. * **Updated the Intel ice driver.** Updated the Intel ice driver with new features and improvements, including: * Added support for device-specific DDP package loading. * Added support for handling Receive Flex Descriptor. * Added support for protocol extraction on per Rx queue. * Added support for Flow Director filter based on generic filter framework. * Added support for the ``RTE_ETH_DEV_CLOSE_REMOVE`` flag. * Generic filter enhancement - Supported pipeline mode. - Supported new packet type like PPPoE for switch filter. * Supported input set change and symmetric hash by rte_flow RSS action. * Added support for GTP Tx checksum offload. * **Added cryptodev asymmetric session-less operation.** Added session-less option to cryptodev asymmetric structure. It works the same way as symmetric crypto, corresponding xform is used directly by the crypto op. * **Updated the Huawei hinic driver.** Updated the Huawei hinic driver with new features and improvements, including: * Enabled SR-IOV - Partially supported at this point, VFIO only. * Supported VLAN filter and VLAN offload. * Supported Unicast MAC filter and Multicast MAC filter. * Supported Flow director for LACP, VRRP, BGP and so on. * Supported FW version get. * **Updated Mellanox mlx5 driver.** Updated Mellanox mlx5 driver with new features and improvements, including: * Added support for VLAN pop flow offload command. * Added support for VLAN push flow offload command. * Added support for VLAN set PCP offload command. * Added support for VLAN set VID offload command. * Added support for matching on packets withe Geneve tunnel header. * **Updated the AF_XDP PMD.** Updated the AF_XDP PMD.

See the :doc:`../cryptodevs/nitrox` guide for more details on this new * **Added asymmetric support to Marvell OCTEON TX crypto PMD.** Added support for asymmetric operations in Marvell OCTEON TX cypto PMD. Supports RSA and modexp operations. * **Added Marvell OCTEON TX2 crypto PMD** Added a new PMD driver for h/w crypto offload block on ``OCTEON TX2`` SoC. See :doc:`../cryptodevs/octeontx2` for more details * **Updated NXP crypto PMDs for PDCP support.** PDCP support is added to DPAA_SEC and DPAA2_SEC PMDs using rte_security APIs. Support is added for all sequence number sizes for control and user plane. Test application is updated for unit testing. * **Enabled Single Pass GCM acceleration on QAT GEN3.** Added support for Single Pass GCM, available on QAT GEN3 only (Intel QuickAssist Technology C4xxx). It is automatically chosen instead of the classic 2-pass mode when running on QAT GEN3, significantly improving the performance of AES GCM operations. * **Updated the Intel QuickAssist Technology (QAT) asymmetric crypto PMD.** * Added support for asymmetric session-less operations. * Added support for RSA algorithm with pair (n, d) private key representation. * Added support for RSA algorithm with quintuple private key representation. * **Updated the Intel QuickAssist Technology (QAT) compression PMD.** Added stateful decompression support in the Intel QuickAssist Technology PMD. Please note that stateful compression is not supported. * **Added external buffers support for dpdk-test-compress-perf tool.** Added a command line option to dpdk-test-compress-perf tool to allocate and use memory zones as external buffers instead of keeping the data directly in mbuf areas. * **Updated the IPSec library.** Added SA Database API to ``librte_ipsec``. A new test-sad application is also introduced to evaluate and perform custom functional and performance tests for IPsec SAD implementation. * **Introduced FIFO for NTB PMD.** Introduced FIFO for NTB (Non-transparent Bridge) PMD to support packet based processing. * **Added eBPF JIT support for arm64.** Added eBPF JIT support for arm64 architecture to improve the eBPF program performance. * **Updated testpmd.** * Added a console command to testpmd app, ``show port (port_id) ptypes`` which gives ability to print port supported ptypes in different protocol layers.
