+-dpdk-pdump Application
+-======================
+-
+-The ``dpdk-pdump`` tool is a Data Plane Development Kit (DPDK) tool that runs as
+-a DPDK secondary process and is capable of enabling packet capture on dpdk ports.
+-
+-   .. Note::
+-
+-      * The ``dpdk-pdump`` tool depends on libpcap based PMD which is disabled
+-        by default in the build configuration files,
+-        owing to an external dependency on the libpcap development files
+-        which must be installed on the board.
+-        Once the libpcap development files are installed, the libpcap based PMD
+-        can be enabled by setting CONFIG_RTE_LIBRTE_PMD_PCAP=y and recompiling the DPDK.
+-
+-
+-Running the Application
+------------------------
+-
+-The tool has a number of command line options:
+-
+-.. code-block:: console
+-
+-   ./build/app/dpdk-pdump --
+-                          --pdump '(port=<port id> | device_id=<pci id or vdev name>),
+-                                   (queue=<queue_id>),
+-                                   (rx-dev=<iface or pcap file> |
+-                                    tx-dev=<iface or pcap file>),
+-                                   [ring-size=<ring size>],
+-                                   [mbuf-size=<mbuf data size>],
+-                                   [total-num-mbufs=<number of mbufs>]'
+-                          [--server-socket-path=<server socket dir>]
+-                          [--client-socket-path=<client socket dir>]
+-
+-The ``--pdump`` command line option is mandatory and it takes various sub arguments which are described in
+-below section.
+-
+-   .. Note::
+-
+-      * Parameters inside the parentheses represents mandatory parameters.
+-
+-      * Parameters inside the square brackets represents optional parameters.
+-
+-      * Multiple instances of ``--pdump`` can be passed to capture packets on different port and queue combinations.
+-
+-The ``--server-socket-path`` command line option is optional. This represents the server socket directory.
+-If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/``
+-for non root users.
+-
+-The ``--client-socket-path`` command line option is optional. This represents the client socket directory.
+-If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/``
+-for non root users.
+-
+-
+-The ``--pdump`` parameters
+-~~~~~~~~~~~~~~~~~~~~~~~~~~
+-
+-``port``:
+-Port id of the eth device on which packets should be captured.
+-
+-``device_id``:
+-PCI address (or) name of the eth device on which packets should be captured.
+-
+-   .. Note::
+-
+-      * As of now the ``dpdk-pdump`` tool cannot capture the packets of virtual devices
+-        in the primary process due to a bug in the ethdev library. Due to this bug, in a multi process context,
+-        when the primary and secondary have different ports set, then the secondary process
+-        (here the ``dpdk-pdump`` tool) overwrites the ``rte_eth_devices[]`` entries of the primary process.
+-
+-``queue``:
+-Queue id of the eth device on which packets should be captured. The user can pass a queue value of ``*`` to enable
+-packet capture on all queues of the eth device.
+-
+-``rx-dev``:
+-Can be either a pcap file name or any Linux iface.
+-
+-``tx-dev``:
+-Can be either a pcap file name or any Linux iface.
+-
+-   .. Note::
+-
+-      * To receive ingress packets only, ``rx-dev`` should be passed.
+-
+-      * To receive egress packets only, ``tx-dev`` should be passed.
+-
+-      * To receive ingress and egress packets separately ``rx-dev`` and ``tx-dev``
+-        should both be passed with the different file names or the Linux iface names.
+-
+-      * To receive ingress and egress packets separately ``rx-dev`` and ``tx-dev``
+-        should both be passed with the same file names or the the Linux iface names.
+-
+-``ring-size``:
+-Size of the ring. This value is used internally for ring creation. The ring will be used to enqueue the packets from
+-the primary application to the secondary. This is an optional parameter with default size 16384.
+-
+-``mbuf-size``:
+-Size of the mbuf data. This is used internally for mempool creation. Ideally this value must be same as
+-the primary application's mempool's mbuf data size which is used for packet RX. This is an optional parameter with
+-default size 2176.
+-
+-``total-num-mbufs``:
+-Total number mbufs in mempool. This is used internally for mempool creation. This is an optional parameter with default
+-value 65535.
+-
+-
+-Example
+--------
+-
+-.. code-block:: console
+-
+-   $ sudo ./build/app/dpdk-pdump -- --pdump 'port=0,queue=*,rx-dev=/tmp/rx.pcap'
