2. DPDK Release 18.02

2.1. New Features

  • Added the ixgbe ethernet driver to support RSS with flow API.

    Rte_flow actually defined to include RSS, but till now, RSS is out of rte_flow. This patch is to support igb and ixgbe NIC with existing RSS configuration using rte_flow API.

  • Add MAC loopback support for i40e.

    Add MAC loopback support for i40e in order to support test task asked by users. According to the device configuration, it will setup TX->RX loopback link or not.

  • Add the support of run time determination of number of queues per i40e VF

    The number of queue per VF is determined by its host PF. If the PCI address of an i40e PF is aaaa:bb.cc, the number of queues per VF can be configured with EAL parameter like -w aaaa:bb.cc,queue-num-per-vf=n. The value n can be 1, 2, 4, 8 or 16. If no such parameter is configured, the number of queues per VF is 4 by default.

  • Added the i40e ethernet driver to support RSS with flow API.

    Rte_flow actually defined to include RSS, but till now, RSS is out of rte_flow. This patch is to support i40e NIC with existing RSS configuration using rte_flow API.It also enable queue region configuration using flow API for i40e.

  • Added NVGRE and UDP tunnels support in Solarflare network PMD.

    Added support for NVGRE, VXLAN and GENEVE tunnels.

    • Added support for UDP tunnel ports configuration.
    • Added tunneled packets classification.
    • Added inner checksum offload.
  • Added the igb ethernet driver to support RSS with flow API.

    Rte_flow actually defined to include RSS, but till now, RSS is out of rte_flow. This patch is to support igb NIC with existing RSS configuration using rte_flow API.

  • Add AVF (Adaptive Virtual Function) net PMD.

    A new net PMD has been added, which supports IntelĀ® Ethernet Adaptive Virtual Function (AVF) with features list below:

    • Basic Rx/Tx burst
    • SSE vectorized Rx/Tx burst
    • Promiscuous mode
    • MAC/VLAN offload
    • Checksum offload
    • TSO offload
    • Jumbo frame and MTU setting
    • RSS configuration
    • stats
    • Rx/Tx descriptor status
    • Link status update/event
  • Updated the AESNI-MB PMD.

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

    • AES-CCM algorithm.
  • Updated the DPAA_SEC crypto driver to support rte_security.

    Updated the dpaa_sec crypto PMD to support rte_security lookaside protocol offload for IPSec.

  • Added Wireless Base Band Device (bbdev) abstraction.

    The Wireless Baseband Device library is an acceleration abstraction framework for 3gpp Layer 1 processing functions that provides a common programming interface for seamless opeartion on integrated or discrete hardware accelerators or using optimized software libraries for signal processing. The current release only supports 3GPP CRC, Turbo Coding and Rate Matching operations, as specified in 3GPP TS 36.212.

    See the Wireless Baseband Device Library programmer’s guide for more details.

  • Added New eventdev OPDL PMD

    The OPDL (Ordered Packet Distribution Library) eventdev is a specific implementation of the eventdev API. It is particularly suited to packet processing workloads that have high throughput and low latency requirements. All packets follow the same path through the device. The order in which packets follow is determinted by the order in which queues are set up. Events are left on the ring until they are transmitted. As a result packets do not go out of order.

    With this change, application can use OPDL PMD by eventdev api.

  • Added New pipeline use case for dpdk-test-eventdev application

    The pipeline case can be used to simulate various stages in a real world application from packet receive to transmit while maintaining the packet ordering also measure the performance of the event device across the stages of the pipeline.

    The pipeline use case has been made generic to work will all the event devices based on the capabilities.

  • Updated Eventdev Sample application to support event devices based on capability

    Updated Eventdev pipeline sample application to support various types of pipelines based on the capabilities of the attached event and ethernet devices. Also, renamed the application from SW PMD specific eventdev_pipeline_sw_pmd to PMD agnostic eventdev_pipeline.
