The new pdump tool is added for packet capturing on dpdk. This tool runs as secondary process by default. Tool facilitates the command line options like port, device_id, queue which user should pass on to the tool to request the packet capture on those devices. Tool creates the rte ring, mempool and pcap vdev and calls the enable API of the pdump library with port/device_id, queue, ring and mempool as arguments to enable the packet capture on specific devices and gets the packets from the primary process over the ring. Once the packets are received, those packets will be send to the pcap vdev. Tool can be terminated by using ctrl+c(SIGINT) upon which tool calls the disable API of the pdump library to disable the packet capture and dequeues the rest of the packets from the ring and sends them on to the pcap vdev, then after releases all allocated resources.
