+	  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.
