> Below is Mellanox's roadmap for DPDK20.05:
>
>
>
> Reduce memory consumption in mlx5 PMD -
>
> [1] Reduce flow memory (entry size) footprint/consumption.
>
> [2] Remove flow rules caching.
>
> Change the mlx5 PMD implementation of rte_eth_dev_stop()/rte_eth_dev_start() to stop caching flow rules (freeing resources for the created flows).
>
> Benefits: Scale and performance improvement.
>
>
>
> HW offload for TTL matching
>
> [3] Offload TTL matching from routing applications to the NIC.
>
> Usage through rte_flow API ; Implementation in mlx5 PMD.
>
> Benefits: Simplifying the routing application complexity as well as reducing host CPU usage through offloading the TTL logic to the NIC.
>
>
>
> Flow aging - Introducing new AGE action in the rte_flow API
>
> [4] Add a new action to allow the application (client) to define an age threshold (seconds) on which it expects to get notification from the mlx5 PMD.
>
> The PMD will implement the flow aging monitoring aging through the use of the rte_flow API, instead of the application.
>
> Additional background can be found in here: https://patchwork.dpdk.org/patch/53701/.
>
>
>
> Add support for additional features in vDPA
>
> [5] Support Large-Send-Offload (LSO).
>
> [6] Improve debuggability through vDPA device counters and error reporting.
>
> [7] Rate limiting - allow application definition of the maximal number of packets; providing means to apply different policies/QoS for different applications / tenants.
>
> [8] ConnectX-6 Dx - introduce HW Doorbell instead of current SW Doorbell.
>
>
>
> Performance improvement for jumbo-frame size
>
> [9] Add support for large MTU size while using MPRQ to provide full line rate performance with any packet size.
>
>
>
> Hairpin with jumbo-frames
>
> [10] Add support for jumbo-frame packets In addition to the existing hairpin offloading functionality.
>
>
>
> Enable GTP encap/decap
>
> [11] Add encap/decap to GTP using the rte_flow raw_encap/raw_decap APIs.
>
>
>
> Adding test application
>
> [12] Introduce a new (standalone) test application for measuring flow insertion rate and traffic performance.
>
> The application defines flows with rte_flow API ; Measure the flow insertion rate and traffic performance.
