+
+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
+- tx/rx_burst
+- Speed capabilities
+- Link status
+- CRC offload
+- Packet type parsing
+
+
+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-4.4.52-armada-17.10
+
+
+- MUSDK (Marvell User-Space SDK) sources
+
+ .. code-block:: console
+
+ git clone git@github.com:Semihalf/marvell-dpdk.git -b musdk-armada-17.10-mvneta
+
+ 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-bpool-dma=64 --enable-pp2=no --enable-neta
+
+- DPDK environment
+
+ Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup
+ DPDK environment.
+
+
+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.
+
+
+Usage example
+^^^^^^^^^^^^^
+
+.. code-block:: console
+
+ ./testpmd --vdev=eth_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-bpool-dma=64
+ 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=eth_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=eth_mvneta,iface=eth0,iface=eth1 -c 3 -- -T 1 -p 3
