Identifying the Adapter
-----------------------

To determine if one or more Pensando DSC 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

Firmware Support
----------------

The ionic PMD requires firmware which supports 16 segment transmit SGLs.
This support was added prior to version 1.0. For help upgrading older versions,
please contact Pensando support.

Building DPDK
-------------

The ionic PMD 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.
