> When binding or unbinding a range of devices, it can be useful to use
> wildcards to specify the devices rather than repeating the same prefix
> multiple times. We can use the python "glob" module to give us this
> functionality - at least for PCI devices - by checking /sys for matching files.

> Examples of use from my system:
> 
>     ./dpdk-devbind.py -b vfio-pci 80:04.*
>     ./dpdk-devbind.py -u 80:04.[2-7]
> 
> The first example binds eight devices, 80:04.0..80:04.7, to vfio-pci. The
> second then unbinds six of those devices, 80:04.2..80:04.7, from any driver.
