Think I got this one (at least).  Regulation is about /not
coexisting/ on the same channel while AUTO-BW is about coexistence on
neighbouring channels (within the same band).

Not yet there with mastering buildroot, sorry, but since I've seen
f78405f landing in the repository -- which I think is the commit you were
referring to -- I did try out a current nightly build (2016-11-05).  But
I can't observe any change in 'iw reg get' output (and I'm still not
sure if iw is telling me wifi is obeying FCC rules or ETSI rules).

tnx, Charles
