1196 | * domain via its regulatory_hint(). After its gets its own regulatory | |
1197 | * domain it will only allow further regulatory domain settings to | |
1198 | * further enhance compliance. For example if channel 13 and 14 are | |
1199 | * disabled by this regulatory domain no user regulatory domain can | |
1200 | * enable these channels at a later time. This can be used for devices | |
1201 | * which do not have calibration information gauranteed for frequencies | |
