[dpdk-dev] [PATCH v2 07/10] doc: refer PMD compile and test section from liquidio doc

Refer the section which explains driver compilation and running of
testpmd in Linux, instead of describing it in driver documentation.

-Driver Compilation
-------------------
-
-To compile LiquidIO PMD for Linux x86_64 gcc target, run the following "make"
-command:
-
-.. code-block:: console
-
-   cd <DPDK-source-directory>
-   make install T=x86_64-native-linuxapp-gcc

-Sample Application Notes
-------------------------
-
-This section demonstrates how to launch ``testpmd`` with LiquidIO® CN23XX
-device managed by ``librte_pmd_lio`` in Linux operating system.

-#. Mount huge pages:
-
-   .. code-block:: console
-
-      mkdir /mnt/huge
-      mount -t hugetlbfs nodev /mnt/huge

-#. Request huge pages:
-
-   .. code-block:: console
-
-      echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
-
-#. Load ``vfio-pci`` driver:
-
-   .. code-block:: console
-
-      modprobe vfio-pci
-
-#. Bind the LiquidIO VFs to ``vfio-pci`` loaded in previous step:
-
-   Setup VFIO permissions for regular users and then bind to ``vfio-pci``:
-
-   .. code-block:: console
-
-      sudo chmod a+x /dev/vfio
-
-      sudo chmod 0666 /dev/vfio/*
-
-      ./usertools/dpdk-devbind.py --bind vfio-pci 0000:03:00.3 0000:03:08.3

-#. Start ``testpmd`` with basic parameters:
-
-   .. code-block:: console
-
-      ./build/app/testpmd -c 0xf -n 4 -- -i
