OK.  Problem is, iw as a moving target seems not to be too well
documented.  Any recommended readings related to how iw reg output
should to be interpreted?

Thanks!  Is that what AVM FritzBoxes call wireless coexistence?  Can't
see the relation to regulation, which is rather about primary and
secondary users /not coexisting/.  Well, as I said, some more iw
documentation could help understanding (Linux) wireless better.

Oh, I'm not a developer, but building custom images with the image
generator so far.  With the recent enabling of IPv6 in the kernel so
that it cannot be disabled by removing some packages in the image
generator, I do have a need to switch to compiling images anyway.  Will
report back (and more problems) when I have kept up with that.  Thanks
