1187 | * ignore regulatory domain settings until it gets its own regulatory | |
1188 | * domain via its regulatory_hint(). After its gets its own regulatory | |
1189 | * domain it will only allow further regulatory domain settings to | |
1190 | * further enhance compliance. For example if channel 13 and 14 are | |
1191 | * disabled by this regulatory domain no user regulatory domain can | |
1192 | * enable these channels at a later time. This can be used for devices | |
1193 | * which do not have calibration information gauranteed for frequencies | |
1194 | * or settings outside of its regulatory domain. | |
