doc: refer PMD compile/test section from ark guide

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

Usage Example
-------------
This section demonstrates how to launch **testpmd** with Atomic Rules ARK
devices managed by librte_pmd_ark.
Follow instructions available in the document
:ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>` to launch
**testpmd** with Atomic Rules ARK devices managed by librte_pmd_ark.
#. Load the kernel modules:
Example output:
.. code-block:: console
.. code-block:: console
modprobe uio
insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
.. note::
The ARK PMD driver depends upon the igb_uio user space I/O kernel module
#. Mount and request huge pages:
.. code-block:: console
mount -t hugetlbfs nodev /mnt/huge
echo 256 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
#. Bind UIO driver to ARK device at 0000:01:00.0 (using dpdk-devbind.py):
.. code-block:: console
./usertools/dpdk-devbind.py --bind=igb_uio 0000:01:00.0
.. note::
The last argument to dpdk-devbind.py is the 4-tuple that indentifies a specific PCIe
device. You can use lspci -d 1d6c: to indentify all Atomic Rules devices in the system,
and thus determine the correct 4-tuple argument to dpdk-devbind.py
#. Start testpmd with basic parameters:
.. code-block:: console
./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
Example output:
.. code-block:: console
