+MVNETA Poll Mode Driver
+=======================
+
+The MVNETA PMD (librte_pmd_mvneta) provides poll mode driver support
+for the Marvell NETA 1/2.5 Gbps adapter.
+
+Detailed information about SoCs that use PPv2 can be obtained here:
+
+* https://www.marvell.com/embedded-processors/armada-3700/
+
+.. Note::
+
+   Due to external dependencies, this driver is disabled by default. It must
+   be enabled manually by setting relevant configuration option manually.
+   Please refer to `Config File Options`_ section for further details.
+
+
+Features
+--------
+
+Features of the MVNETA PMD are:
+
+- Start/stop
+- tx/rx_queue_setup
+- Speed capabilities
+- Jumbo frame
+- CRC offload
+
+
+Limitations
+-----------
+
+- Flushing vlans added for filtering is not possible due to MUSDK missing
+  functionality. Current workaround is to reset board so that NETA has a
+  chance to start in a sane state.
+
+Prerequisites
+-------------
+
+- Custom Linux Kernel sources
+
+  .. code-block:: console
+
+     git clone https://github.com/MarvellEmbeddedProcessors/linux-marvell.git -b linux-4.4.120-armada-18.09
+
+
+- MUSDK (Marvell User-Space SDK) sources
+
+  .. code-block:: console
+
+     git clone https://github.com/MarvellEmbeddedProcessors/musdk-marvell.git -b musdk-armada-18.09
+
+  MUSDK is a light-weight library that provides direct access to Marvell's
+  NETA. Alternatively prebuilt MUSDK library can be
+  requested from `Marvell Extranet <https://extranet.marvell.com>`_. Once
+  approval has been granted, library can be found by typing ``musdk`` in
+  the search box.
+
+  MUSDK must be configured with the following features:
+
+  .. code-block:: console
+
+     --enable-pp2=no --enable-neta
+
+- DPDK environment
+
+  Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup
+  DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_MVNETA_PMD`` (default ``n``)
+
+    Toggle compilation of the librte_pmd_mvneta driver.
+
+Runtime options
+~~~~~~~~~~~~~~~
+
+The following ``devargs`` options can be enabled at runtime. They must
+be passed as part of EAL arguments.
+
+- ``iface`` (mandatory, with no default value)
+
+  The name of port (owned by MUSDK) that should be enabled in DPDK.
+  This options can be repeated resulting in a list of ports to be
+  enabled.  For instance below will enable ``eth0`` and ``eth1`` ports.
+
+.. code-block:: console
+
+   ./testpmd --vdev=net_mvneta,iface=eth0,iface=eth1 \
+    -c 3 -- -i --p 3 -a
+
+
+Building DPDK
+-------------
+
+Driver needs precompiled MUSDK library during compilation.
+
+.. code-block:: console
+
+   export CROSS_COMPILE=<toolchain>/bin/aarch64-linux-gnu-
+   ./bootstrap
+   ./configure --host=aarch64-linux-gnu --enable-pp2=no --enable-neta
+   make install
+
+MUSDK will be installed to `usr/local` under current directory.
+For the detailed build instructions please consult ``doc/musdk_get_started.txt``.
+
+Before the DPDK build process the environmental variable ``LIBMUSDK_PATH`` with
+the path to the MUSDK installation directory needs to be exported.
+
+.. code-block:: console
+
+   export LIBMUSDK_PATH=<musdk>/usr/local
+   export CROSS=aarch64-linux-gnu-
+   make config T=arm64-armv8a-linuxapp-gcc
+   sed -ri 's,(MVNETA_PMD=)n,\1y,' build/.config
+   make
+
+Usage Example
+-------------
+
+MVNETA PMD requires extra out of tree kernel modules to function properly.
+`musdk_uio` and `mv_neta_uio` sources are part of the MUSDK. Please consult
+``doc/musdk_get_started.txt`` for the detailed build instructions.
+
+.. code-block:: console
+
+   insmod musdk_uio.ko
+   insmod mv_neta_uio.ko
+
+Additionally interfaces used by DPDK application need to be put up:
+
+.. code-block:: console
+
+   ip link set eth0 up
+   ip link set eth1 up
+
+In order to run testpmd example application following command can be used:
+
+.. code-block:: console
+
+   ./testpmd --vdev=net_mvneta,iface=eth0,iface=eth1 -c 3 -- \
+     -i --p 3 -a --txd 256 --rxd 128 --rxq=1 --txq=1  --nb-cores=1
+
+
+In order to run l2fwd example application following command can be used:
+
+.. code-block:: console
+
+   ./l2fwd --vdev=net_mvneta,iface=eth0,iface=eth1 -c 3 -- -T 1 -p 3
