[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 reducin= g 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 th= reshold (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 t= he rte_flow API, instead of the application. Additional background can be found in here: https://patchwork.dpdk.org/patc= h/53701/. Add support for additional features in vDPA [5] Support Large-Send-Offload (LSO). [6] Improve debuggability through vDPA device counters and erro= r reporting. [7] Rate limiting - allow application definition of the maximal= number of packets; providing means to apply different policies/QoS for dif= ferent 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 hairp= in 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 fl= ow insertion rate and traffic performance.
