Some countries have strict RF restrictions where changing the regulatory
domain dynamically based on the connected AP is not acceptable.
This patch disables Beacon country IE hinting when a valid country code
is set from usersland (e.g., by system using iw or CRDA).

Sorry for the late response, I just noticed that I completely forgot to
review this one.
In principle, it makes sense to me to ignore the country IE in this
case, however I don't understand why the change is done in the mt7921
driver. Isn't this a generic issue that should be consistent across
drivers and thus better handled in mac80211?
Thanks,
