1166 | * ignore regulatory domain settings until it gets its own regulatory | |
1167 | * domain via its regulatory_hint(). After its gets its own regulatory | |
1168 | * domain it will only allow further regulatory domain settings to | |
1169 | * further enhance compliance. For example if channel 13 and 14 are | |
1170 | * disabled by this regulatory domain no user regulatory domain can | |
1171 | * enable these channels at a later time. This can be used for devices | |
1172 | * which do not have calibration information gauranteed for frequencies | |
1173 | * or settings outside of its regulatory domain. | |
1174 | * @WIPHY_FLAG_DISABLE_BEACON_HINTS: enable this if your driver needs to ensure | |
1175 | * that passive scan flags and beaconing flags may not be lifted by | |
1176 | * cfg80211 due to regulatory beacon hints. For more information on beacon | |
37184244 | 1177 | * hints read the documenation for regulatory_hint_found_beacon() |

1179 | * wiphy at all | |
1180 | * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled | |
1181 | * by default -- this flag will be set depending on the kernel's default | |
1182 | * on wiphy_new(), but can be changed by the driver if it has a good | |
1183 | * reason to override the default | |
