I'm not sure how this helps with the initial problem
when using kvargs with key-only.
I think you should continue fixing kvargs API and usage.

About a generic argparse library, I imagine it could simplify DPDK internal parsing.
I have doubts about making it a public library as it is not really a DPDK goal.
The DMA example looks better with argparse so I imagine we want it.

I think this library would have a bigger value
if we integrate some specific syntax parsing
like coremask/corelist as done in another patchset:
