* we will disregard the first regulatory hint (when the
* initiator is %REGDOM_SET_BY_CORE). Drivers that use
* wiphy_apply_custom_regulatory() should have this flag set
* or the regulatory core will set it for the wiphy.
* @REGULATORY_STRICT_REG: tells us that the wiphy for this device
* has regulatory domain that it wishes to be considered as the
* superset for regulatory rules. After this device gets its regulatory
* domain programmed further regulatory hints shall only be considered
* for this device to enhance regulatory compliance, forcing the
* device to only possibly use subsets of the original regulatory
* rules. For example if channel 13 and 14 are disabled by this
* device's regulatory domain no user specified regulatory hint which
* has these channels enabled would enable them for this wiphy,
* the device's original regulatory domain will be trusted as the
* base. You can program the superset of regulatory rules for this
* wiphy with regulatory_hint() for cards programmed with an
* ISO3166-alpha2 country code. wiphys that use regulatory_hint()
* will have their wiphy->regd programmed once the regulatory
* domain is set, and all other regulatory hints will be ignored
* until their own regulatory domain gets programmed.
* @REGULATORY_DISABLE_BEACON_HINTS: enable this if your driver needs to
* ensure that passive scan flags and beaconing flags may not be lifted by
* cfg80211 due to regulatory beacon hints. For more information on beacon
* hints read the documenation for regulatory_hint_found_beacon()
* @REGULATORY_COUNTRY_IE_FOLLOW_POWER: for devices that have a preference
* that even though they may have programmed their own custom power
* setting prior to wiphy registration, they want to ensure their channel
* power settings are updated for this connection with the power settings
* derived from the regulatory domain. The regulatory domain used will be
* based on the ISO3166-alpha2 from country IE provided through
* regulatory_hint_country_ie()
* @REGULATORY_COUNTRY_IE_IGNORE: for devices that have a preference to ignore
* all country IE information processed by the regulatory core. This will
* override %REGULATORY_COUNTRY_IE_FOLLOW_POWER as all country IEs will
