    • Added new action: RTE_FLOW_ACTION_TYPE_AGE to set the timeout and the application flow context for each flow.
    • Added new event: RTE_ETH_EVENT_FLOW_AGED for the driver to report that there are new aged-out flows.
    • Added new query: rte_flow_get_aged_flows to get the aged-out flows contexts from the port.
  • ethdev: Added a new value to link speed for 200Gbps

  • Updated Mellanox mlx5 driver.

    Updated Mellanox mlx5 driver with new features and improvements, including:

    • Added support for the mbufs with external pinned buffers.
    • Added support for RSS using L3/L4 source/destination only.
    • Added support for matching on GTP tunnel header item.
    • Added support for IPv4/IPv6 DSCP rewrite action.
    • Added support for creating Relaxed Ordering Memory Regions.
    • Added support for jumbo frame size (9K MTU) in Multi-Packet RQ mode.
    • Optimized the memory consumption of flow.
    • Added support for flow aging based on hardware counter.
    • Added support for configuring Hairpin queue data buffer size.
    • Removed flow rules caching for memory saving and compliance with ethdev API.
    • Added support for flow pattern with wildcard VLAN item (without VID value).
    • Updated support for matching on GTP header, added match on GTP flags.
  • Added vDPA device APIs to query virtio queue statistics.

    • Added new PMD devarg reclaim_mem_mode.
    • Added new devarg lacp_by_user.
  • Added new testpmd forward mode.

    Added new 5tswap forward mode to testpmd. the 5tswap swaps source and destination in layers 2,3,4 for ipv4 and ipv6 in L3 and UDP and TCP in L4.

  • Added flow performance test application.

    Added new application to test rte_flow performance, including:

    • Measure rte_flow insertion rate.
    • Measure rte_flow deletion rate.
