It is a lot of info, easily repeated 3 times on boot, but it's also the
only real chance to determine why you ended up with the regulatory 
domain settings you got, rather than just the values itself. Given that
a lot (most?) of officially shipping wireless devices are misconfigured
(wrong EEPROM regdom settings for the region they're sold in) and 
considering that the limits can even change at runtime (IEEE 802.11d), 
it is imho quite important not just to be able what the current 
restrictions (iw reg get) are, but also why the kernel settled on those.
