Patch doesn't apply cleanly, not sure why, CI seems having same problem:

If UEFI secure boot is enabled, the Linux kernel may disallow the use of
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``.
+ ``vfio-pci`` kernel module rather than any UIO-based module.
For more details see :ref:`linux_gsg_binding_kernel` below.
Should we change the order of the kernel drivers, currently first section is
"UIO" and second section is "VFIO". Since we encoruage vfio and move igb_uio out
of the repo, should we list the "VfIO" first?
