I would simply remove this script.

Binding devices can be done with either driverctl (which is available
in most distributions) and dpdk-devbind.py (which a Howto already in
the doc).


As for permissions, what this script is doing is scary.
I would prefer users don't rely on this:
usertools/dpdk-setup.sh:        sudo chmod a+x /dev/vfio
usertools/dpdk-setup.sh:        sudo chmod 0666 /dev/vfio/*

OVS uses a udev rule for non root support:

We could describe this in the DPDK documentation.
