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. ======================================================= * **Enabled new devargs parser.** * Enabled devargs syntax ``bus=X,paramX=x/class=Y,paramY=y/driver=Z,paramZ=z`` * Added bus-level parsing of the devargs syntax. * Kept compatibility with the legacy syntax as parsing fallback. * **Added new RSS offload types for IPv4/L4 checksum in RSS flow.** Added macros ETH_RSS_IPV4_CHKSUM and ETH_RSS_L4_CHKSUM, now IPv4 and TCP/UDP/SCTP header checksum field can be used as input set for RSS. * **Updated Broadcom bnxt PMD.** * Added flow offload support for Thor. * Implement support for tunnel offload. * Updated HWRM API to version 1.10.2.44 * **Updated Intel iavf driver.** * Added Intel iavf support on Windows. * Added IPv4 and L4 (TCP/UDP/SCTP) checksum hash support in RSS flow. * **Updated Intel ice driver.** * Added 1PPS out support by a devargs. * Added IPv4 and L4 (TCP/UDP/SCTP) checksum hash support in RSS flow. * Added DEV_RX_OFFLOAD_TIMESTAMP support. * Added timesync API support under scalar path. * **Updated Intel ixgbe driver.** * Added Intel ixgbe support on Windows. * **Updated Marvell cnxk ethdev driver.** * Added rte_flow support for dual VLAN insert and strip actions. * Added rte_tm support. * **Updated Marvell cnxk crypto PMD.** * Added AES-CBC SHA1-HMAC support in lookaside protocol (IPsec) for CN10K. * Added Transport mode support in lookaside protocol (IPsec) for CN10K. * Added UDP encapsulation support in lookaside protocol (IPsec) for CN10K. * Added support for lookaside protocol (IPsec) offload for CN9K. * **Added support for event crypto adapter on Marvell CN10K and CN9K.** * Added event crypto adapter OP_FORWARD mode support. * **Updated NXP dpaa_sec crypto PMD.** * Added DES-CBC, AES-XCBC-MAC, AES-CMAC and non-HMAC algo support. * Added PDCP short MAC-I support. * **Updated NXP dpaa2_sec crypto PMD.** * Added PDCP short MAC-I support. * **Added multi-process support for testpmd.** Added command-line options to specify total number of processes and current process ID. Each process owns subset of Rx and Tx queues. * **Updated test-crypto-perf application with new cases.** * Added support for asymmetric crypto throughput performance measurement. Only modex is supported for now. * **Added lookaside protocol (IPsec) tests in dpdk-test.** * Added known vector tests (AES-GCM 128, 192, 256). * Added tests to verify error reporting with ICV corruption. * Added tests to verify IV generation. * Added tests to verify UDP encapsulation. * Added tests to validate packets soft expiry. * Added tests to validate packets hard expiry. * Added tests to verify tunnel header verification in IPsec inbound. 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. ======================================================= * eal: Removed the deprecated function ``rte_get_master_lcore()`` and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``. * eal: The old api arguments that were deprecated for blacklist/whitelist are removed. Users must use the new block/allow list arguments. * i40e: Removed i40evf driver. iavf already became the default VF driver for i40e devices, so there is no need to maintain i40evf. 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. ======================================================= * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been removed. Its usages have been replaced by a new function ``rte_kvargs_get_with_value()``. * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure to ``src_addr`` and ``dst_addr``, respectively. * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to rte_cryptodev_is_valid_dev as it can be used by the application as well as PMD to check whether the device is valid or not. * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.* as it is for drivers only and should be private to DPDK, and not installed for app use. * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was renamed to ``aux_flags`` to indicate warnings and other information from the crypto/security operation. This field will be used to communicate events such as soft expiry with IPsec in lookaside mode. 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. ======================================================= * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata`` routines used by inline outbound and inline inbound security processing were made inline and enhanced to do simple 64-bit set/get for PMDs that do not have much processing in PMD specific callbacks but just 64-bit set/get. This avoids a per packet function pointer jump overhead for such PMDs. * security: A new option ``iv_gen_disable`` was added in structure ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD, so that application can provide its own IV and test known test vectors. * security: A new option ``tunnel_hdr_verify`` was added in structure ``rte_security_ipsec_sa_options`` to indicate whether outer header verification need to be done as part of inbound IPsec processing. * security: A new structure ``rte_security_ipsec_lifetime`` was added to replace ``esn_soft_limit`` in IPsec configuration structure ``rte_security_ipsec_xform`` to allow applications to configure SA soft and hard expiry limits. Limits can be either in number of packets or bytes. 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. =======================================================
