Use proper spelling, capitalization and punctuation in all sections. Variable and config names should be quoted as fixed width text: ``LIKE_THIS``. Build the docs and view the output file to ensure the changes are correct:: ninja -C build doc xdg-open build/doc/guides/html/rel_notes/release_26_03.html New Features ------------ .. 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 (ordered alphabetically by vendor name) - 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 custom memory allocation hooks in ACL library.** Added a hook API mechanism allowing applications to provide their own allocation and free functions for ACL runtime memory. * **Updated AMD axgbe ethernet driver.** * Added support for V4000 Krackan2e. * **Updated CESNET nfb ethernet driver.** * The timestamp value has been updated to make it usable. * **Updated Google Virtual Ethernet (gve) driver.** * Added application-initiated device reset. * **Updated Intel iavf driver.** * Added support for pre and post VF reset callbacks. * **Updated Marvell cnxk net driver.** * Added out-of-place support for CN20K SoC. * **Updated ZTE zxdh ethernet driver.** * Added support for modifying queue depth. * Optimized queue allocation resources. * Added support for setting link speed and getting auto-negotiation status. * Added support for secondary processes. * Added support for GENEVE TSO and tunnel outer UDP Rx checksum. * **Added 256-NEA/NCA/NIA algorithms in cryptodev library.** Added support for following wireless algorithms: * NEA4, NIA4, NCA4: Snow 5G confidentiality, integrity and AEAD modes. * NEA5, NIA5, NCA5: AES 256 confidentiality, integrity and AEAD modes. * NEA6, NIA6, NCA6: ZUC 256 confidentiality, integrity and AEAD modes. * **Updated openssl crypto driver.** * Added support for AES-XTS cipher algorithm. * Added support for SHAKE-128 and SHAKE-256 authentication algorithms. * **Added Ctrl+L support to cmdline library.** Added handling of the key combination Control+L to clear the screen before redisplaying the prompt. 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. ======================================================= * **Discontinued support for AMD Solarflare SFN7xxx family boards.** 7000 series adaptors are out of support in terms of hardware. * **Removed the SSE vector paths from some Intel drivers.** The SSE path was not widely used, so it was removed from the i40e, iavf and ice drivers. Each of these drivers have faster vector paths (AVX2 and AVX-512) which have feature parity with the SSE paths, and a fallback scalar path which also has feature parity. 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. ======================================================= * **Added additional length checks for name parameter lengths.** Several library functions now have additional name length checks instead of silently truncating. * lpm: name must be less than RTE_LPM_NAMESIZE. * hash: name parameter must be less than RTE_HASH_NAMESIZE. * efd: name must be less than RTE_EFD_NAMESIZE. * tailq: name must be less than RTE_TAILQ_NAMESIZE. * cfgfile: name must be less than CFG_NAME_LEN and value must be less than CFG_VALUE_LEN. * **Updated the pcapng library.** * The length of comment strings is now validated. Maximum allowable length is 2^16-1 because of pcapng file format. 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 25.11. 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. This section is a comment. Do not overwrite or remove it. Also, make sure to start the actual text at the margin. ======================================================= Tested Platforms ---------------- .. This section should contain a list of platforms that were tested with this release. The format is: * platform with combinations * List of CPU * List of OS * List of devices * Other relevant details... This section is a comment. Do not overwrite or remove it. Also, make sure to start the actual text at the margin. =======================================================
