Stylistic note.
Please don't break messages across multiple lines, it makes it harder to
read, and also harder for users to search for error messages.

If you are concerned about checkpatch, checkpatch allows long lines for
messages.

		PMD_INIT_LOG(ERR,
			     "Failed allocation for MAC address");

+IGC Poll Mode Driver
+======================
+
+The IGC PMD (librte_pmd_igc) provides poll mode driver support for Foxville
+I225 Series Network Adapters.
+
+- For information about I225, please refer to:
+  `https://ark.intel.com/content/www/us/en/ark/products/series/184686/
+  intel-ethernet-controller-i225-series.html`
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+Please note that enabling debugging options may affect system performance.
+
+- ``CONFIG_RTE_LIBRTE_IGC_PMD`` (default ``y``)
+
+  Toggle compilation of the ``librte_pmd_igc`` driver.
+
+- ``CONFIG_RTE_LIBRTE_IGC_DEBUG_*`` (default ``n``)
+
+  Toggle display of generic debugging messages.
+
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
