+Armada device plugin
+=====================
+
+Overview
+--------
+
+This plugins provides native device support for Marvell PP2 network
+device, found in Marvel Armada family of SOCs.
+It uses Marvell Usermode SDK
+(`MUSDK <https://github.com/MarvellEmbeddedProcessors/musdk-marvell>`__).
+
+Prerequisites
+-------------
+
+Plugins depends on installed MUSDK and Marvell provided linux in Marvell SDK.
+Following kernel modules from MUSDK must be loaded for plugin to work:
+``musdk_cma.ko``
+``mv_pp_uio.ko``
+
+Musdk 18.09.3 compilation steps
+-------------------------------
+
+::
+
+   ./bootstrap
+   ./configure --prefix=/opt/vpp/external/aarch64/ CFLAGS="-Wno-error=unused-result -g -fPIC" --enable-shared=no
+   sed -i -e  's/marvell,mv-pp-uio/generic-uio/' modules/pp2/mv_pp_uio.c
+   sed -i -e  's/O_CREAT/O_CREAT, S_IRUSR | S_IWUSR/' src/lib/file_utils.c
+   make
+   sudo make install
+
+Usage
+-----
+
+Interface Creation and Deletion
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Interfaces are using new vnet dev APIs, CLIs or startup.conf to create and
+delete interfaces.
+
+Sample startup.conf:
+
+::
+
+   devices {
+     dev platform/f2000000.ethernet {
+       port 1 { name ppio1 }
+   }
+
+Device identifier in this example is 'platform/f2000000.ethernet' where
+'platform' is bus name and 'f2000000.ethernet' is linux platform bus
+identifier for specific PP2.
+
+Platform identifier can be found in sysfs:
+
+::
+
+   $ ls /sys/bus/platform/devices | grep ethernet
+   f2000000.ethernet

-Marvell device plugin
-=====================
-
-Overview
---------
-
-This plugins provides native device support for Marvell PP2 network
-device, by use of Marvell Usermode SDK
-(`MUSDK <https://github.com/MarvellEmbeddedProcessors/musdk-marvell>`__).
-Code is developed and tested on
-`MACCHIATObin <http://macchiatobin.net>`__ board.
-
-Prerequisites
--------------
-
-Plugins depends on installed MUSDK and Marvell provided linux
-`kernel <https://github.com/MarvellEmbeddedProcessors/linux-marvell>`__
-with MUSDK provided kernel patches (see ``patches/linux`` in musdk repo
-and relevant documentation. Kernel version used: **4.14.22
-armada-18.09.3** MUSDK version used: **armada-18.09.3** Following kernel
-modules from MUSDK must be loaded for plugin to work: \*
-``musdk_cma.ko`` \* ``mv_pp_uio.ko``
-
-Musdk 18.09.3 compilation steps
--------------------------------
-
-::
-
-   ./bootstrap
-   ./configure --prefix=/opt/vpp/external/aarch64/ CFLAGS="-Wno-error=unused-result -g -fPIC" --enable-shared=no
-   sed -i -e  's/marvell,mv-pp-uio/generic-uio/' modules/pp2/mv_pp_uio.c
-   sed -i -e  's/O_CREAT/O_CREAT, S_IRUSR | S_IWUSR/' src/lib/file_utils.c
-   make
-   sudo make install
-
-Usage
------
-
-Interface Creation
-~~~~~~~~~~~~~~~~~~
-
-Interfaces are dynamically created with following CLI:
-
-::
-
-   create interface marvell pp2 name eth0
-   set interface state mv-ppio-0/0 up
-
-Where ``eth0`` is linux interface name and ``mv-ppio-X/Y`` is VPP
-interface name where X is PP2 device ID and Y is PPIO ID Interface needs
-to be assigned to MUSDK in FDT configuration and linux interface state
-must be up.
-
-Interface Deletion
-~~~~~~~~~~~~~~~~~~
-
-Interface can be deleted with following CLI:
-
-::
-
-   delete interface marvell pp2 <interface name>
-
-Interface Statistics
-~~~~~~~~~~~~~~~~~~~~
-
-Interface statistics can be displayed with
-``sh hardware-interface mv-ppio0/0`` command.
-
-Interaction with DPDK plugin
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This plugin doesn’t have any dependency on DPDK or DPDK plugin but it
-can work with DPDK plugin enabled or disabled. It is observed that
-performance is better around 30% when DPDK plugin is disabled, as DPDK
-plugin registers own buffer manager, which needs to deal with additional
-metadata in each packet.
-
-DPKD plugin can be disabled by adding following config to the
-startup.conf.
-
-::
-
-   plugins {
-     dpdk_plugin.so { disable }
-   }
