DPDK Release 17.08

New Features

  • Added support for generic flow API (rte_flow) on igb NIC.

    This API provides a generic means to configure hardware to match specific ingress or egress traffic, alter its behavior and query related counters according to any number of user-defined rules.

    • Generic flow API support for Ethernet, IPv4, UDP, TCP and RAW pattern items with QUEUE actions. There are four type of filter support for this feature on igb.

  • Added Generic Flow API support to enic.

    Flow API support for outer Ethernet, VLAN, IPv4, IPv6, UDP, TCP, SCTP, VxLAN and inner Ethernet, VLAN, IPv4, IPv6, UDP and TCP pattern items with QUEUE, MARK, FLAG and VOID actions for ingress traffic.

  • Added support for Chelsio T6 family of adapters

    CXGBE PMD updated to run Chelsio T6 family of adapters.

  • Added latency and performance improvements for cxgbe

    TX and RX path reworked to improve performance. Also reduced latency for slow traffic.

  • Updated bnxt PMD.

    Major enhancements include:
    • Support MTU modification.
    • Support LRO.
    • Support VLAN filter and strip functionality.
    • Other enhancements to add support for more dev_ops.
    • Add PMD specific APIs mainly to control VF from PF.
    • Update HWRM version to 1.7.7

  • Added support for Rx interrupts on mlx4 driver.

    Rx queues can be armed with an interrupt which will trigger on the next packet arrival.

  • Updated szedata2 PMD.

    Added support for firmwares with multiple Ethernet ports per physical port.

  • Reorganized the symmetric crypto operation structure.

    The crypto operation (rte_crypto_sym_op) has been reorganized as follows:

    • Removed field rte_crypto_sym_op_sess_type.
    • Replaced pointer and physical address of IV with offset from the start of the crypto operation.
    • Moved length and offset of cipher IV to rte_crypto_cipher_xform.
    • Removed Additional Authentication Data (AAD) length.
    • Removed digest length.
    • Removed AAD pointer and physical address from auth structure.
    • Added aead structure, containing parameters for AEAD algorithms.

  • Reorganized the crypto operation structure.

    The crypto operation (rte_crypto_op) has been reorganized as follows:

    • Added field rte_crypto_op_sess_type.
    • Enumerations rte_crypto_op_status and rte_crypto_op_type have been modified to be uint8_t values.
    • Removed the field opaque_data.
    • Pointer to rte_crypto_sym_op has been replaced with a zero length array.

  • Reorganized the crypto symmetric session structure.

    The crypto symmetric session structure (rte_cryptodev_sym_session) has been reorganized as follows:

    • dev_id field has been removed.
    • driver_id field has been removed.
    • Mempool pointer mp has been removed.
    • Replaced private marker with array of pointers to private data sessions sess_private_data.
  • Updated cryptodev library.
    • Added AEAD algorithm specific functions and structures, so it is not necessary to use a combination of cipher and authentication structures anymore.
    • Added helper functions for crypto device driver identification.
    • Added support for multi-device sessions, so a single session can be used in multiple drivers.
    • Added functions to initialize and free individual driver private data with a same session.

  • Updated dpaa2_sec crypto PMD.

    Added support for AES-GCM and AES-CTR

  • Updated the AESNI MB PMD.

    The AESNI MB PMD has been updated with additional support for:

    • 12-byte IV on AES Counter Mode, apart from the previous 16-byte IV.

  • Updated the AES-NI GCM PMD.

    The AES-NI GCM PMD was migrated from the ISA-L library to the Multi Buffer library, as the latter library has Scatter Gather List support now. The migration entailed adding additional support for:

    • 192-bit key.

  • Updated the Cryptodev Scheduler PMD.

    Added a multicore based distribution mode, which distributes the enqueued crypto operations among several slaves, running on different logical cores.

API Changes

  • Reworked rte_cryptodev library.

    The rte_cryptodev library has been reworked and updated. The following changes have been made to it:

    • The crypto device type enumeration has been removed from cryptodev library.
    • The function rte_crypto_count_devtype() has been removed, and replaced by the new function rte_crypto_count_by_driver().
    • Moved crypto device driver names definitions to the particular PMDs. These names are not public anymore.
    • rte_cryptodev_configure() does not create the session mempool for the device anymore.
    • rte_cryptodev_queue_pair_attach_sym_session() and rte_cryptodev_queue_pair_dettach_sym_session() functions require the new parameter device id.
    • Modified parameters of rte_cryptodev_sym_session_create(), to accept mempool, instead of device id and rte_crypto_sym_xform.
    • Remove device id parameter from rte_cryptodev_sym_session_free().

ABI Changes

  • Reorganized the crypto operation structures.

    Some fields have been modified in the rte_crypto_op and rte_crypto_sym_op structures, as described in the New Features section.

  • Reorganized the crypto symmetric session structure.

    Some fields have been modified in the rte_cryptodev_sym_session structure, as described in the New Features section.

  • Reorganized the ``rte_crypto_sym_cipher_xform`` structure.
    • Added cipher IV length and offset parameters.
  • Reorganized the ``rte_crypto_sym_auth_xform`` structure.
    • Added authentication IV length and offset parameters.
    • Changed field size of AAD length from uint32_t to uint16_t.
    • Changed field size of digest length from uint32_t to uint16_t.
    • Removed AAD length.
  • Replaced dev_type enumeration with uint8_t driver_id in rte_cryptodev_info and rte_cryptodev structures.
  • Removed session_mp from rte_cryptodev_config.
