The purpose is to provide comfortable programming interface for virtual switch software (such as OVS) to take advantage of incoming device's vSwitch acceleration capability when using DPDK as data plane. Below is summary of changes: 1. Support to specify flow's destination as an ethdev interface. Add action RTE_FLOW_ACTION_TYPE_ETHDEV_PORT, use port_id as the identification of the destitation. A typical use case is, with a smart NIC used for vSwitch acceleration, flow is defined to redirect packet between switch port that is managed by a Port Representor. See patch for Port Representor: http://dpdk.org/dev/patchwork/patch/31458/ 2. Enhanced flow statistics query. Enhanced action RTE_FLOW_ACTION_COUNT by adding last hit timestamp tracking which is the requirement from OVS. 3. Add flow timeout support as the requirement from OVS Application is able to a) Setup the time duration of a flow, the flow is expected to be deleted automatically when timeout. b) Ping a flow to check if it is active or not. c) Register a callback function when a flow is deleted due to timeout. 4. Add protocol headers which will be supported by incoming device. New protocal headers include IPV4 ARP, IPV6 ICMP , IPV6 extent header. 5. Add packet modification actions which will be supported by incoming device. Add new actions that be used to modify packet content with generic semantic: RTE_FLOW_ACTION_TYPE_FIELD_UPDATE: update specific field of packet RTE_FLWO_ACTION_TYPE_FIELD_INCREMENT: increament specific field of packet RTE_FLWO_ACTION_TYPE_FIELD_DECREMENT: decreament specific field of packet RTE_FLWO_ACTION_TYPE_FIELD_COPY: copy data from one field to another in packet. All action use struct rte_flow_item parameter to match the pattern that going to be modified, if no pattern match, the action just be skipped. These action are non-terminating action. they will not impact the fate of the packets, since pattern match is expected to be performed before packet be modified. Note: The RFC patch is based on v17.11. Testpmd command line support is not included. v2: - v1 is incompelete due to some misoperation.
