I apologize for the late notice. This is Mellanox's roadmap for DPDK19.08, which we are working on currently.
Introduce rte_flow APIs for: * Matching and modification for TCP ACK and TCP SEQ. * Setting Metadata in RX and receiving it as part of mbuf, to have more info from packet processing in the NIC. * Matching on GRE key. * Flow aging APIs, to offload application aging logic. * Hairpin, which acts as a "bump on the wire". Those APIs will be supported via mlx5 PMD for ConnectX-5 NIC, BlueField SmartNIC and above. Addition to mlx5 PMD (supporting ConnectX-5 NIC, BlueField SmartNIC and above): * HW offload for IP-in-IP inner RSS. * HW offload for matching on ICMP. * HW offload for matching TCP flags. * HW offload for LRO (Large Receive Offload), intended to reduce host CPU overhead when processing Rx TCP packets * Robustness additions in data-path for completions error handling and recovery. * Improvement of rte_flow_query rate and latency of application's call. * Out of the box performance improvements by consolidating several TX functions to a single one (ConnectX-5 on x86 host)
