+dpdk-devbind Application
+========================
+
+The ``dpdk-devbind`` tool is a Data Plane Development Kit (DPDK) utility
+that helps binding and unbinding devices from specific drivers.
+As well as checking their status in that regard.
+
+
+Running the Application
+-----------------------
+
+The tool has a number of command line options:
+
+.. code-block:: console
+
+   dpdk-devbind [options] DEVICE1 DEVICE2 ....
+
+OPTIONS
+-------
+
+* ``--help, --usage``
+
+        Display usage information and quit
+
+* ``-s, --status``
+
+        Print the current status of all known network interfaces.
+        For each device, it displays the PCI domain, bus, slot and function,
+        along with a text description of the device. Depending upon whether the
+        device is being used by a kernel driver, the ``igb_uio`` driver, or no
+        driver, other relevant information will be displayed:
+        - the Linux interface name e.g. ``if=eth0``
+        - the driver being used e.g. ``drv=igb_uio``
+        - any suitable drivers not currently using that device e.g. ``unused=igb_uio``
+        NOTE: if this flag is passed along with a bind/unbind option, the
+        status display will always occur after the other operations have taken
+        place.
+
+* ``-b driver, --bind=driver``
+
+        Select the driver to use or "none" to unbind the device
+
+* ``-u, --unbind``
+
+        Unbind a device (Equivalent to ``-b none``)
+
+* ``--force``
+
+        By default, devices which are used by Linux - as indicated by having
+        routes in the routing table - cannot be modified. Using the ``--force``
+        flag overrides this behavior, allowing active links to be forcibly
+        unbound.
+        WARNING: This can lead to loss of network connection and should be used
+        with caution.
+
+
+.. warning::
+
+    Due to the way VFIO works, there are certain limitations to which devices can be used with VFIO.
+    Mainly it comes down to how IOMMU groups work.
+    Any Virtual Function device can be used with VFIO on its own, but physical devices will require either all ports bound to VFIO,
+    or some of them bound to VFIO while others not being bound to anything at all.
+
+    If your device is behind a PCI-to-PCI bridge, the bridge will then be part of the IOMMU group in which your device is in.
+    Therefore, the bridge driver should also be unbound from the bridge PCI device for VFIO to work with devices behind the bridge.
+
+.. warning::
+
+    While any user can run the ``dpdk-devbind.py`` script to view the status of the network ports,
+    binding or unbinding network ports requires root privileges.
+
+
+Examples
+--------
+
+To display current device status::
+
+   dpdk-devbind --status
+
+To bind eth1 from the current driver and move to use igb_uio::
+
+   dpdk-devbind --bind=igb_uio eth1
+
+To unbind 0000:01:00.0 from using any driver::
+
+   dpdk-devbind -u 0000:01:00.0
+
+To bind 0000:02:00.0 and 0000:02:00.1 to the ixgbe kernel driver::
+
+   dpdk-devbind -b ixgbe 02:00.0 02:00.1
+
+To check status of all network ports, assign one to the igb_uio driver and check status again::
+
+   # Check the status of the available devices.
+   dpdk-devbind --status
+   Network devices using DPDK-compatible driver
+   ============================================
+   <none>
+
+   Network devices using kernel driver
+   ===================================

+   sudo dpdk-devbind -b igb_uio 0000:0a:00.0
+
+
+   # Recheck the status of the devices.
+   dpdk-devbind --status
+   Network devices using DPDK-compatible driver
+   ============================================

+
+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 can only be used in conjunction with a primary
+        application which has the packet capture framework initialized already.
+
+      * 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 together, ``rx-dev`` and ``tx-dev``
+        should both be passed with the same file name or the same Linux iface name.
+
+``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'

+dpdk-procinfo Application
+=========================
+
+The dpdk-procinfo application is a Data Plane Development Kit (DPDK) application
+that runs as a DPDK secondary process and is capable of retrieving port
+statistics, resetting port statistics and printing DPDK memory information.
+This application extends the original functionality that was supported by
+dump_cfg.
+
+Running the Application
+-----------------------
+The application has a number of command line options:
+
+.. code-block:: console
+
+   ./$(RTE_TARGET)/app/dpdk-procinfo -- -m | [-p PORTMASK] [--stats | --xstats |
+   --stats-reset | --xstats-reset]
+
+Parameters
+~~~~~~~~~~
+**-p PORTMASK**: Hexadecimal bitmask of ports to configure.
+
+**--stats**
+The stats parameter controls the printing of generic port statistics. If no
+port mask is specified stats are printed for all DPDK ports.
+
+**--xstats**
+The stats parameter controls the printing of extended port statistics. If no
+port mask is specified xstats are printed for all DPDK ports.
+
+**--stats-reset**
+The stats-reset parameter controls the resetting of generic port statistics. If
+no port mask is specified, the generic stats are reset for all DPDK ports.
+
+**--xstats-reset**
+The xstats-reset parameter controls the resetting of extended port statistics.
+If no port mask is specified xstats are reset for all DPDK ports.
+
+**-m**: Print DPDK memory information.
