dpdk-devbind.py ./. bonding interfaces

[qcqx-obaq.6cba8489@hashmail.org]

To whom it may concern.

usertools/dpdk-devbind.py currently does not recognize interfaces 
that are part of a bond as active.
that can be a nuisance if you are using something like libmoon which
proactively rebinds drivers for all "not active" interfaces.

yes, i am aware of the dpdk contribution guideline. 

no, i am not going to jump through linux-kernel level hoops for
a trivial 9-sloc-python driveby-contrib.

yes, that glorious code is all written by me, i promise i didnt
steal it, and whoever takes pity and merges it is free to claim
full credits for it.
(if you feel bad about claiming credits for something you didnt
 write, perhaps find more useful names for "f" and "l" and/or
 add some comment above it...)

yes, i promise i will read and respect the contrib guide if i ever
want to contrib code that took longer to write than it takes to
read the contrib guide.
