[dpdk-dev] [PATCH DPDK-KMODS] igb_uio: add compile instructions

[Anatoly Burakov <anatoly.burakov@intel.com>]

Currently, compilation instructions for igb_uio are missing. Add them,
as well as a top-level INSTALL file referring users to per-OS
subdirectories.

+Building Linux Drivers
+======================
+
+Prerequisites
+-------------
+
+The system must have relevant Linux kernel headers or source code installed.
+
+Build
+-----
+
+To build ``igb_uio`` driver, simple run ``make`` command inside the
+``linux/igb_uio`` directry:
+
+.. code-block:: console
+
+    cd linux/igb_uio
+    make
+
+If compiling against a specific kernel source directory is required, it is
+possible to specify the kernel source directory using the ``KSRC`` variable:
+
+.. code-block:: console
+
+    make KSRC=/path/to/custom/kernel/source
+
+Load the driver
+---------------
+
+The ``igb_uio`` driver requires the UIO driver to be loaded beforehand (these
+commands are to be run as ``root`` user):
+
+.. code-block:: console
+
+    modprobe uio
+    insmod igb_uio.ko
+
+Clean the build directory
+-------------------------
+
+To clean the build directory, the following command can be run:
+
+.. code-block:: console
+
+    make clean
