Hi,
thanks for the contribution. However, in order to aid reviewing and merging
of new drivers, the policy in DPDK is that the driver be split into logically
distinct patches, rather than a single massive patch. For contributing
guidelines see [1], and especially see the section on new drivers [2], and
the subsection within that on patch splitting [3].
Thanks,
/Bruce

This should be a separate patch.
Please run a python checker like flake8 and cleanup.

dpdk-devbind.py:629:32: E231 missing whitespace after ','
Also, it would probably better to encourage users to use another tool
like driverctl, rather than adding more complexity to dpdk-devbind.
That was the response I got when looking to add vmbus support to devbind.
