Primary process will act as server, forks a child secondary process. Secondary process acts as client. Server will do pdump init to serve any pdump client requests. Server will create a vdev, send/receive packets continuously in a separate thread. Client will create virtual rings to receive the packet dump. Client sends pdump enable/disable requests using either port/device id. Packet flow direction can be tx/rx/tx&rx. In Server, appropriate pdump callbacks are triggered, when packets are transmitted/received. Pdump packet is copied to client rings.
