+IONIC Driver
+============
+
+The ionic driver provides support for Pensando server adapters.
+It currently supports the below models:
+
+- `Naples DSC-25 <https://pensando.io/assets/documents/Naples-25_ProductBrief_10-2019.pdf>`_
+- `Naples DSC-100 <https://pensando.io/assets/documents/Naples_100_ProductBrief-10-2019.pdf>`_
+
+Please visit https://pensando.io for more information.
+
+Identifying the Adapter
+-----------------------
+
+To find if one or more Pensando PCI Ethernet devices are installed
+on the host, check for the PCI devices:
+
+   .. code-block:: console
+
+      lspci -d 1dd8:
+      b5:00.0 Ethernet controller: Device 1dd8:1002
+      b6:00.0 Ethernet controller: Device 1dd8:1002
+
+Pre-Installation Configuration
+------------------------------
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_IONIC_PMD`` (default ``y``)
+
+  Toggle compilation of ionic PMD.
+
+Building DPDK
+-------------
+
+The ionic PMD driver supports UIO and VFIO, please refer to the
+:ref:`DPDK documentation that comes with the DPDK suite <linux_gsg>`
+for instructions on how to build DPDK.
