+   UIO on the system. Therefore, devices for use by DPDK should be bound to the
+   ``vfio-pci`` kernel module rather than ``igb_uio`` or ``uio_pci_generic``.
+   For more details see :ref:`linux_gsg_binding_kernel` below.

 Since DPDK release 1.7 onward provides VFIO support, use of UIO is optional
 for platforms that support using VFIO.
