DPDK Release 19.05

New Features

  • Added Stack API.

    Added a new stack API for configuration and use of a bounded stack of pointers. The API provides MT-safe push and pop operations that can operate on one or more pointers per operation.

    The library supports two stack implementations: standard (lock-based) and lock-free. The lock-free implementation is currently limited to x86-64 platforms.

  • Added Lock-Free Stack Mempool Handler.

    Added a new lock-free stack handler, which uses the newly added stack library.

  • Updated KNI module and PMD.

    Updated the KNI kernel module to set the max_mtu according to the given initial MTU size. Without it, the maximum MTU was 1500.

    Updated the KNI PMD driver to set the mbuf_size and MTU based on the given mb-pool. This provide the ability to pass jumbo frames if the mb-pool contains suitable buffers' size.

  • Added the AF_XDP PMD.

    Added a Linux-specific PMD driver for AF_XDP, it can create the AF_XDP socket and bind it to a specific netdev queue, it allows a DPDK application to send and receive raw packets through the socket which would bypass the kernel network stack to achieve high performance packet processing.

  • Added a net PMD NFB.

    Added the new nfb net driver for Netcope NFB cards. See the ../nics/nfb NIC guide for more details on this new driver.

  • Added IPN3KE net PMD.

    Added the new ipn3ke net driver for Intel® FPGA PAC(Programmable Acceleration Card) N3000. See the ../nics/ipn3ke NIC guide for more details on this new driver.

    Aside from this, ifpga_rawdev is also updated to support Intel® FPGA PAC N3000 with SPI interface access, I2C Read/Write and Ethernet PHY configuration.

  • Updated Solarflare network PMD.

    Updated the sfc_efx driver including the following changes:

    • Added support for Rx descriptor status and related API in a secondary process.
    • Added support for Tx descriptor status API in a secondary process.
    • Added support for RSS RETA and hash configuration get API in a secondary process.
    • Added support for Rx packet types list in a secondary process.
    • Added Tx prepare to do Tx offloads checks.
    • Added support for VXLAN and GENEVE encapsulated TSO.

  • Updated Mellanox drivers.

    New features and improvements were done in mlx4 and mlx5 PMDs:

    • Added firmware version reading.

  • Renamed avf to iavf.

    Renamed Intel Ethernet Adaptive Virtual Function driver avf to iavf, which includes the directory name, lib name, filenames, makefile, docs, macros, functions, structs and any other strings in the code.

  • Updated the enic driver.
    • Fixed several flow (director) bugs related to MARK, SCTP, VLAN, VXLAN, and inner packet matching.
    • Added limited support for RAW.
    • Added limited support for RSS.
    • Added limited support for PASSTHRU.

  • Updated the ixgbe driver.

    New features for VF:

    • Added promiscuous mode support.
  • Updated the ice driver.
    • Added support of SSE and AVX2 instructions in Rx and Tx paths.
    • Added package download support.
    • Added Safe Mode support.
    • Supported RSS for UPD/TCP/SCTP+IPV4/IPV6 packets.

  • Updated the i40e driver.

    New features for PF:

    • Added support for VXLAN-GPE packet.
    • Added support for VXLAN-GPE classification.

  • Updated the ENETC driver.

    New features:

    • Added physical addressing mode support
    • Added SXGMII interface support
    • Added basic statistics support
    • Added promiscuous and allmulticast mode support
    • Added MTU update support
    • Added jumbo frame support
    • Added queue start/stop
    • Added CRC offload support
    • Added Rx checksum offload validation support

  • Updated the QuickAssist Technology PMD.

    Added support for AES-XTS with 128 and 256 bit AES keys.

  • Updated AESNI-MB PMD.

    Added support for out-of-place operations.

  • Updated the IPsec library.

    The IPsec library has been updated with AES-CTR and 3DES-CBC cipher algorithms support. The related ipsec-secgw test scripts have been added.

  • Updated the testpmd application.

    Improved testpmd application performance on ARM platform. For macswap forwarding mode, NEON intrinsics were used to do swap to save CPU cycles.

Removed Items

API Changes

  • eal: the type of the attr_value parameter of the function rte_service_attr_get() has been changed from uint32_t * to uint64_t *.
  • meter: replace enum rte_meter_color in meter library with new rte_color definition added in 19.02. To consolidate mulitple color definitions replicated at many places such as: rte_mtr.h, rte_tm.h, replacements with rte_color values are done.
  • vfio: Functions rte_vfio_container_dma_map and rte_vfio_container_dma_unmap have been extended with an option to request mapping or un-mapping to the default vfio container fd.

ABI Changes

  • ethdev: Additional fields in rte_eth_dev_info.

    The rte_eth_dev_info structure has had two extra fields added: min_mtu and max_mtu. Each of these are of type uint16_t. The values of these fields can be set specifically by the PMD drivers as supported values can vary from device to device.

  • cryptodev: in 18.08 new structure rte_crypto_asym_op was introduced and included into rte_crypto_op. As rte_crypto_asym_op structure was defined as cache-line aligned that caused unintended changes in rte_crypto_op structure layout and alignment. Remove cache-line alignment for rte_crypto_asym_op to restore expected rte_crypto_op layout and alignment.

Known Issues

  • No software AES-XTS implementation.

    There are currently no cryptodev software PMDs available which implement support for the AES-XTS algorithm, so this feature can only be used if compatible hardware and an associated PMD is available.
