-# Marvell device plugin for VPP {#marvell_plugin_doc}
-
-##Overview
-This plugins provides native device support for Marvell PP2 network device, by use of Marvell Usermode SDK ([MUSDK][1]).
-Code is developed and tested on [MACCHIATObin][2] board.
-
-##Prerequisites
-Plugins depends on installed MUSDK and Marvell provided linux [kernel][3] 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 Cration
-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 performace 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 }
-}
-```
