[Shijith Thotton]

Add a new document with steps to build PMDs and launch a sample test
application, "testpmd". It can be included in other PMD documentations
or be referred.

+
+Driver Compilation
+------------------
+
+To compile 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
+
+FreeBSD targets should use "gmake" command instead of "make".
+
+For more information, refer :ref:`Getting Started Guide for Linux <linux_gsg>` or
+:ref:`Getting Started Guide for FreeBSD <freebsd_gsg>` depending on your platform.
+
+
+
+Running testpmd in Linux
+------------------------
+
+This section demonstrates how to launch ``testpmd`` in Linux.
+
+#. 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 ``igb_uio`` or ``vfio-pci`` driver:
+
+   .. code-block:: console
+
+      modprobe uio
+      insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
+
+   or
+
+   .. code-block:: console
+
+      modprobe vfio-pci
+
+#. Setup VFIO permissions for regular users before binding to ``vfio-pci``:
+
+   .. code-block:: console
+
+      sudo chmod a+x /dev/vfio
+
+      sudo chmod 0666 /dev/vfio/*
+
+#. Bind the adapters to ``igb_uio`` or ``vfio-pci`` loaded in the previous step:
+
+   .. code-block:: console
+
+      ./usertools/dpdk-devbind.py --bind igb_uio DEVICE1 DEVICE2
+
+   Or setup VFIO permissions for regular users and then bind to ``vfio-pci``:
+
+   .. code-block:: console
+
+      ./usertools/dpdk-devbind.py --bind vfio-pci DEVICE1 DEVICE2
+
+   .. note::
+
+       DEVICE1, DEVICE2 are specified via PCI "domain:bus:slot.func" syntax
+       or "bus:slot.func" syntax.
+
+#. Start ``testpmd`` with basic parameters:
+
+   .. code-block:: console
+
+      ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- -i
