1. DPDK Release 26.03

1.1. New Features

  • 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 AF_PACKET ethernet driver.

    • Added support for multi-segment mbuf reception to handle jumbo frames with standard mbuf sizes when scatter Rx offload is enabled.

  • Updated CESNET nfb ethernet driver.

    • The timestamp value has been updated to make it usable.

    • The DPDK port has been changed to represent just one Ethernet port instead of all Ethernet ports on the NIC.

    • Added port device argument to select a subset of all ports.

    • Added firmware version, correct Ethernet link speed and maximum MTU reporting.

    • Common CESNET-NDK-based adapters have been added, including the FB2CGHH (Silicom Denmark) and XpressSX AGI-FH400G (Reflex CES).

    • Added support for configuration of the RS-FEC mode, link up / down state, and the Rx MTU.

  • Updated Google Virtual Ethernet (gve) driver.

    • Added application-initiated device reset.

    • Added support for receive flow steering.

  • Updated Huawei hinic3 ethernet driver.

    • Added support for Huawei’s new SPx NICs, including SP230 and SP920 (DPU).

    • Added support for GENEVE tunnel TSO and IP-in-IP tunnel TSO on the SP230.

    • Added support for VXLAN-GPE checksum on the SP620.

    • Added support for tunnel packet outer UDP checksum.

    • Added support for QinQ on the SP620.

    • Added AVX2 vectorized split queue Rx and Tx paths.

  • Updated Marvell cnxk net driver.

    • Added out-of-place support for CN20K SoC.

    • Added plain packet reassembly support for CN20K SoC.

    • Added IPsec Rx inject 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 the 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 Marvell cnxk crypto driver.

    • Added support for Snow 5G NEA4/NIA4 and ZUC 256 NEA6/NIA6 for CN20K platform.

  • Updated openssl crypto driver.

    • Added support for AES-XTS cipher algorithm.

    • Added support for SHAKE-128 and SHAKE-256 authentication algorithms.

    • Added support for SHA3-224, SHA3-256, SHA3-384, and SHA3-512 hash algorithms and their HMAC variants.

  • Added automatic deferred free on hash data overwrite.

    When RCU is configured with a free_key_data_func callback, rte_hash_add_key_data now automatically defers freeing the old data pointer on key overwrite via the RCU defer queue.

  • Added Ctrl+L support to cmdline library.

    Added handling of the key combination Ctrl+L to clear the screen before redisplaying the prompt.

1.2. Removed Items

  • 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 has 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.

1.3. API Changes

  • 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 the pcapng file format.

1.4. ABI Changes

  • No ABI change that would break compatibility with 25.11.
