i'm trying to set my wifi's regulatory domain.
currently, with
cat /etc/modprobe.d/wifi.conf
options iwlwifi lar_disable=1
softdep ath pre: cfg80211
options cfg80211 ieee80211_regdom=US
cat /etc/modules-load.d/wifi.conf
iwlwifi

it's

i want to set it explicitly to = US
crda's apparently no longer the method,
git clone git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/crda.git
cat crda/README
...
CRDA is no longer needed as of kernel v4.15 since commit 007f6c5e6eb45
("cfg80211: support loading regulatory database as firmware file") added
support to use the kernel's firmware request API which looks for the
firmware on /lib/firmware. Because of this CRDA is legacy software for
older kernels. It will continue to be maintained.

attempt to SET with `iw` fails
iw reg set --debug US
not a valid ISO/IEC 3166-1 alpha2
Special non-alpha2 usable entries:

note,
there's discussion here
https://bugzilla.kernel.org/show_bug.cgi?id=205695
about rm'ing lar_disable options 'vs' being unable to set the reg dom,
https://unix.stackexchange.com/questions/286258/intel-wireless-7265d-iw-shows-wrong-regulatory-information
not clear what to _do_ abt that, here.
what's the correct/current config+method for setting the wifi intfc's reg domain?
