When using full offload, all traffic will be handled by the HW, and forwarded to the requested VF or wire and the control application does not see this traffic anymore. So there's a need for an action that enables the control application some forwarded traffic visibility. The solution introduces a new action that will sample the incoming traffic and send a duplicated traffic with the specified ratio to the application, while the original packet will continue to the target destination. The packets sampled equals is '1/ratio', the ratio value set to 1 means that the packets will be completely mirrored. The sample packet can be assigned with different set of actions from the original packet. In order to support the sample packet in rte_flow, new rte_flow action definition RTE_FLOW_ACTION_TYPE_SAMPLE and structure rte_flow_action_sample will be introduced.
