The first spelling issue is fixed in main:
https://git.dpdk.org/dpdk/commit/?id=d0db11a82609

The other three warnings (all of them about "test-args") are
introduced by this patch, and this is a problem: once merged, I
understand any following patch will get flagged as failing this check.
There may be something better to do for the mid/long term, but the
quicker is to add test-args to UNH dictionnary.
Once done, I can merge this patch.

Lincoln, Brandon?
