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. ======================================================= * **Enhanced ethdev representor syntax.** * Introduced representor type of VF, SF and PF. * Supported sub-function and multi-host in representor syntax:: representor=# [0,2-4] /* Legacy VF compatible. */ representor=[[c#]pf#]vf# c1pf2vf3 /* VF 3 on PF 2 of controller 1. */ representor=[[c#]pf#]sf# sf[0,2-1023] /* 1023 SFs. */ representor=[c#]pf# c2pf[0,1] /* 2 PFs on controller 2. */ * **Updated Arkville PMD driver.** Updated Arkville net driver with new features and improvements, including: * Generalized passing meta data between PMD and FPGA, allowing up to 20 bytes of user specified information in RX and TX paths. * Updated dynamic PMD extensions API using standardized names. * Added support for new Atomic Rules PCI device IDs ``0x100f, 0x1010, 0x1017, 0x1018, 0x1019``. * **Updated Broadcom bnxt driver.** * Updated HWRM structures to 1.10.2.15 version. * **Updated Hisilicon hns3 driver.** * Added support for module EEPROM dumping. * Added support for freeing Tx mbuf on demand. * Added support for copper port in Kunpeng930. * Added support for runtime config to select IO burst function. * Added support for outer UDP checksum in Kunpeng930. * Added support for query Tx descriptor status. * Added support for query Rx descriptor status. * **Updated Intel iavf driver.** Updated the Intel iavf driver with new features and improvements, including: * Added flow filter to support GTPU inner L3/L4 fields matching. * **Updated NXP DPAA driver.** * Added support for shared ethernet interface. * Added support for external buffers in Tx. * **Updated NXP DPAA2 driver.** * Added support for traffic management. * Added support for configurable Tx confirmation. * Added support for external buffers in Tx. * **Updated Wangxun txgbe driver.** * Added support for txgbevf PMD. * Support device arguments to handle AN training for backplane NICs. * **Enabled vmxnet3 PMD on Windows.** * **Updated the AF_XDP driver.** * Added support for preferred busy polling. * **Updated testpmd.** * Added a command line option to configure forced speed for Ethernet port. ``dpdk-testpmd -- --eth-link-speed N`` * Added command to display Rx queue used descriptor count. ``show port (port_id) rxq (queue_id) desc used count`` 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. ======================================================= 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. ======================================================= * eal: The experimental TLS API added in ``rte_thread.h`` has been renamed from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy and confusion with the transport layer security term. 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_legacy_register`` has been removed from the public API and is now an internal-only function. This function was already marked as internal in the API documentation for it, and was not for use by external applications. Known Issues ------------ .. This section should contain new known issues in this release. Sample format: * **Add title in present tense with full stop.** Add a short 1-2 sentence description of the known issue in the present tense. Add information on any known workarounds.
