  In order to allow binding/unbinding of devices for use by the
ntb_rawdev, we need to update the devbind script to add a new class
of device, and add device ids for the specific HW instances. And
only support Intel Skylake platform right now.

+Device Setup
+------------
+
+The Intel NTB devices need to be bound to a DPDK-supported kernel driver
+to use, i.e. igb_uio, vfio. The ``dpdk-devbind.py`` script can be used to
+show devices status and to bind them to a suitable kernel driver. They will
+appear under the category of "Misc (rawdev) devices".
