In linux kernel since version 3.16 (release Date: 2014-08-03)  
This option enables support for parsing regulatory hints
from cellular base stations. If enabled and at least one driver
claims support for parsing cellular base station hints the
regulatory core will allow and parse these regulatory hints.
The regulatory core will only apply these regulatory hints on
drivers that support this feature. You should only enable this
feature if you have tested and validated this feature on your
systems.
