3. DPDK Release 25.11

3.1. New Features

  • Added automatic lcore-id remapping option.

    Added the EAL option --remap-lcore-ids or -R to enable automatic remapping of lcore-ids to a contiguous set starting from 0, or from a user-provided value. When this flag is passed, the lcores specified by core mask or core list options are taken as the physical cores on which the application will run, and one thread will be started per core, with sequential lcore-ids. For example: dpdk-test -l 140-144 -R will start 5 threads with lcore-ids 0 to 4 on physical cores 140 to 144.

  • Added inter-process and inter-OS DMA device API.

    • Added parameters in DMA device virtual channel to configure DMA operations that span across different processes or operating system domains.
    • Added functions to exchange handlers between DMA devices.

  • Added 800G speed.

    Added Ethernet link speed for 800 Gb/s as it is well standardized in IEEE, and some devices already support this speed.

  • Added mbuf tracking for debug.

    Added history dynamic field in mbuf to store successive states of the mbuf lifecycle. Some functions were added to dump statistics. A script was added to parse mbuf tracking stored in a file. This feature is disabled by default.

  • Added ethdev API to get link connector.

    Added API to report type of link connector for a port. The following connectors are enumerated:

    • None
    • Twisted Pair
    • Attachment Unit Interface (AUI)
    • Optical Fiber Link
    • BNC
    • Direct Attach Copper
    • XFI, SFI
    • Media Independent Interface (MII)
    • SGMII, QSGMII
    • XLAUI, GAUI, AUI, CAUI, LAUI
    • SFP, SFP+, SFP28, SFP-DD
    • QSFP, QSFP+, QSFP28, QSFP56, QSFP-DD
    • OTHER

    By default, it reports RTE_ETH_LINK_CONNECTOR_NONE unless the driver specifies it.

  • Updated Amazon ENA (Elastic Network Adapter) ethernet driver.

    • Added support for retrieving HW timestamps for Rx packets with nanosecond resolution.
    • Fixed PCI BAR mapping on 64K page size.

  • Added Huawei hinic3 ethernet driver.

    Added network driver for the Huawei SPx series Network Adapters.

  • Updated Intel ice ethernet driver.

    • Added support for Data Center Bridging (DCB).
    • Added support for Priority Flow Control (PFC).

  • Updated Marvell cnxk ethernet driver.

    Added support to set/get link configuration as outlined below:

    • Get speed capability from firmware.
    • Report link type, mode and status.
    • Configure link mode.

  • Added Nebulamatrix nbl ethernet driver.

    Added the PMD for Nebulamatrix NICs.

  • Updated NVIDIA mlx5 driver.

    • Added support for NVIDIA ConnectX-9 SuperNIC adapters.
    • Added support for count and age flow actions on root tables with HW steering flow engine.

  • Updated NXP DPAA2 ethernet driver.

    • Enabled software taildrop for ordered queues.
    • Added additional MAC counters in xstats.

  • Added NXP ENETC4 ethernet driver.

    Added ENETC4 PMD for multiple new generation SoCs.

  • Updated TAP ethernet driver.

    • Replaced ioctl-based link control with a Netlink-based implementation.
    • Linux net devices can now be renamed without breaking link control.
    • Linux net devices can now be moved to different namespaces without breaking link control (requires Linux >= 5.2).

  • Updated Wangxun txgbe ethernet driver.

    Added support for Wangxun Amber-Lite NIC series, including FF5025 (supporting 10G and 25G) and FF5040 (supporting 40G). As these new models share hardware similarities with the existing 10G Sapphire NICs, many of the existing configurations and practices are expected to apply.

  • Updated Yunsilicon xsc ethernet driver.

    • Added FW version query.
    • Added TSO support.
    • Added module EEPROM dump.
    • Added promiscuous mode.
    • Added link status.
    • Added link event.
    • Added FEC get and set.
    • Added multi-process per port.
    • Optimized code.

  • Added PQC ML algorithms in cryptodev.

    • Added PQC ML-KEM support with reference to FIPS203.
    • Added PQC ML-DSA support with reference to FIPS204.

  • Updated openssl crypto driver.

    • Added support for PQC ML-KEM and ML-DSA algorithms.

  • Updated Intel QuickAssist Technology (QAT) crypto driver.

    • Added SM2 encryption and decryption algorithms.

  • Renamed HiSilicon DMA driver.

    Renamed dma/hisilicon to dma/hisi_pciep (PCIe internal endpoint) to reflect hardware IP.

  • Added HiSilicon Accelerator DMA driver.

    Kunpeng SoC has an internal accelerator unit which includes zip function, and the zip also supports data copy and fill. This driver exposes this capability to DPDK applications.

  • Added RCU support in the FIB6 library.

    It is now possible to register an RCU QSBR object to handle graceful deletion of table groups.

  • Added packet capture (pdump) for secondary process.

    Added multi-process support to allow packets sent and received by secondary process to be visible in packet capture.

  • Allow overriding the automatic usage/help generation in argparse library.

    The argparse library now supports overriding the automatic help text generation, by allowing the user to provide a custom function to generate the output text. The built-in help text function is available as a public function which can be reused by custom functions, if so desired.

3.2. Removed Items

  • build: as previously announced in the deprecation notices, the enable_kmods build option has been removed. Kernel modules will now be built automatically for OSes where out-of-tree kernel modules are required for DPDK operation. Currently, this means that modules will only be built for FreeBSD. No modules are shipped with DPDK for either Linux or Windows.
  • ethdev: As previously announced in deprecation notes, queue specific stats fields are now removed from struct rte_eth_stats. Affected fields are: q_ipackets, q_opackets, q_ibytes, q_obytes, q_errors. Queue stats will be received via the xstats API instead. Also, the compile time flag RTE_ETHDEV_QUEUE_STAT_CNTRS is removed from public headers.
  • telemetry: As previously announced in the deprecation notices, the functions rte_tel_data_add_array_u64 and rte_tel_data_add_dict_u64 are removed. They are replaced by rte_tel_data_add_array_uint and rte_tel_data_add_dict_uint respectively.
  • net/mlx5: The repr_matching_en device argument has been removed. Applications which disabled this option were able to receive traffic from any physical port/VF/SF on any representor port. Specifically, in most cases, this was used to process all traffic on a representor port which is a transfer proxy port. Similar behavior in mlx5 PMD can be achieved without this device argument, by using RTE_FLOW_ACTION_TYPE_RSS in transfer flow rules.

3.3. API Changes

  • rawdev: Changed the return type of rte_rawdev_get_dev_id() to allow negative error values.
  • pcapng: Changed the API for adding interfaces to include a link type argument. The link type was previously hardcoded to the Ethernet link type in the API. This argument is added to rte_pcapng_add_interface.
  • bitmap: Changed the return type of rte_bitmap_free() to void for consistency with other free functions.

3.4. ABI Changes

  • eal: The structure rte_mp_msg alignment has been updated to 8 bytes to limit unaligned accesses in messages payload.
  • stack: The structure rte_stack_lf_head alignment has been updated to 16 bytes to avoid unaligned accesses.
  • ethdev: Added link_connector field to rte_eth_link structure to report the type of link connector for a port.
  • cryptodev: The rte_crypto_sm2_op_param struct member cipher to hold ciphertext is changed to a union data type. This change is required to support partial SM2 calculation which is driven by RTE_CRYPTO_SM2_PARTIAL capability flag.
  • cryptodev: The enum rte_crypto_asym_xform_type, struct rte_crypto_asym_xform and struct rte_crypto_asym_op are updated to include new values to support ML-KEM and ML-DSA.
