In DPDK the ``testpmd`` application can be used to initialize the packet -capture framework and act as a server, and the ``dpdk-pdump`` tool acts as a +capture framework and acts as a server, and the ``dpdk-pdump`` tool acts as a client. To view Rx or Tx packets of ``testpmd``, the application should be launched first, and then the ``dpdk-pdump`` tool. Packets from ``testpmd`` will be sent to the tool, which then sends them on to the Pcap PMD device and
