This section should contain new features added in this release. Sample format: * **Add a title in the past tense with a full stop.** Add a short 1-2 sentence description in the past tense. 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. Do not overwrite or remove it. Also, make sure to start the actual text at the margin. ========================================================= * **Added Wait Until Equal API.** A new API has been added to wait for a memory location to be updated with a 16-bit, 32-bit, 64-bit value. * **Updated rte_flow api to support L2TPv3 over IP flows.** Added support for new flow item to handle L2TPv3 over IP rte_flow patterns. * **Updated Hisilicon hns3 driver.** Updated Hisilicon hns3 driver with new features and improvements, including: * Added support for Rx interrupt. * Added support setting VF MAC address by PF driver. * **Updated the Intel ice driver.** Updated the Intel ice driver with new features and improvements, including: * Added support for MAC rules on specific port. * Added support for MAC/VLAN with TCP/UDP in switch rule. * Added support for 1/10G device. * **Updated Intel iavf driver.** Updated iavf PMD with new features and improvements, including: * Added more supported device IDs. * Updated virtual channel to latest AVF spec. * **Updated Intel i40e driver.** Updated i40e PMD with new features and improvements, including: * Added support for L2TPv3 over IP profiles which can be programmed by the dynamic device personalization (DDP) process. * Added support for ESP-AH profiles which can be programmed by the dynamic device personalization (DDP) process. * Added PF support Malicious Device Drive event catch and notify. * Added LLDP support. * Extended PHY access AQ cmd. * Added support for reading LPI counters. * Added support for Energy Efficient Ethernet * **Updated Mellanox mlx5 driver.** Updated Mellanox mlx5 driver with new features and improvements, including: * Added support for RSS using L3/L4 source/destination only. * **Updated testpmd application.** Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd application. * **Added algorithms to cryptodev API.** * Chacha20-Poly1305 AEAD algorithm can now be supported in cryptodev. * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to asymmetric crypto library specifications. * ECPM (Elliptic Curve Point Multiplication) is added to asymmetric crypto library specifications. * **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.** Added handling of mixed algorithms in encrypted digest hash-cipher (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware. Such algorithm combinations are not supported on GEN1/GEN2 hardware and executing the request returns RTE_CRYPTO_OP_STATUS_INVALID_SESSION. * **Updated the Intel QuickAssist Technology (QAT) symmetric crypto PMD.** Added Chacha20-Poly1305 AEAD algorithm. * **Added Marvell OCTEON TX2 End Point rawdev PMD.** Added a new OCTEON TX2 rawdev PMD for End Point mode of operation. See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD. Removed Items ------------- .. This section should contain removed items in this release.
