92 * enum ieee80211_regulatory_flags - device regulatory flags
93 *
94 * @REGULATORY_CUSTOM_REG: tells us the driver for this device
95 * has its own custom regulatory domain and cannot identify the
96 * ISO / IEC 3166 alpha2 it belongs to. When this is enabled
97 * we will disregard the first regulatory hint (when the
98 * initiator is %REGDOM_SET_BY_CORE). Drivers that use
99 * wiphy_apply_custom_regulatory() should have this flag set
100 * or the regulatory core will set it for the wiphy.
101 * If you use regulatory_hint() *after* using
102 * wiphy_apply_custom_regulatory() the wireless core will
103 * clear the REGULATORY_CUSTOM_REG for your wiphy as it would be
104 * implied that the device somehow gained knowledge of its region.
105 * @REGULATORY_STRICT_REG: tells us that the wiphy for this device
106 * has regulatory domain that it wishes to be considered as the
107 * superset for regulatory rules. After this device gets its regulatory
108 * domain programmed further regulatory hints shall only be considered
109 * for this device to enhance regulatory compliance, forcing the
110 * device to only possibly use subsets of the original regulatory
111 * rules. For example if channel 13 and 14 are disabled by this
112 * device's regulatory domain no user specified regulatory hint which
113 * has these channels enabled would enable them for this wiphy,
114 * the device's original regulatory domain will be trusted as the
115 * base. You can program the superset of regulatory rules for this
116 * wiphy with regulatory_hint() for cards programmed with an
117 * ISO3166-alpha2 country code. wiphys that use regulatory_hint()
118 * will have their wiphy->regd programmed once the regulatory
119 * domain is set, and all other regulatory hints will be ignored
120 * until their own regulatory domain gets programmed.
121 * @REGULATORY_DISABLE_BEACON_HINTS: enable this if your driver needs to
122 * ensure that passive scan flags and beaconing flags may not be lifted by
123 * cfg80211 due to regulatory beacon hints. For more information on beacon
124 * hints read the documentation for regulatory_hint_found_beacon()
125 * @REGULATORY_COUNTRY_IE_FOLLOW_POWER: for devices that have a preference
126 * that even though they may have programmed their own custom power
127 * setting prior to wiphy registration, they want to ensure their channel
128 * power settings are updated for this connection with the power settings
129 * derived from the regulatory domain. The regulatory domain used will be
130 * based on the ISO3166-alpha2 from country IE provided through
131 * regulatory_hint_country_ie()
132 * @REGULATORY_COUNTRY_IE_IGNORE: for devices that have a preference to ignore
133 * all country IE information processed by the regulatory core. This will
134 * override %REGULATORY_COUNTRY_IE_FOLLOW_POWER as all country IEs will
135 * be ignored.
136 * @REGULATORY_ENABLE_RELAX_NO_IR: for devices that wish to allow the
137 * NO_IR relaxation, which enables transmissions on channels on which
138 * otherwise initiating radiation is not allowed. This will enable the
139 * relaxations enabled under the CFG80211_REG_RELAX_NO_IR configuration
140 * option
141 * @REGULATORY_WIPHY_SELF_MANAGED: for devices that employ wiphy-specific
142 * regdom management. These devices will ignore all regdom changes not
143 * originating from their own wiphy.
144 * A self-managed wiphys only employs regulatory information obtained from
145 * the FW and driver and does not use other cfg80211 sources like
146 * beacon-hints, country-code IEs and hints from other devices on the same
147 * system. Conversely, a self-managed wiphy does not share its regulatory
148 * hints with other devices in the system. If a system contains several
149 * devices, one or more of which are self-managed, there might be
150 * contradictory regulatory settings between them. Usage of flag is
151 * generally discouraged. Only use it if the FW/driver is incompatible
152 * with non-locally originated hints.
153 * This flag is incompatible with the flags: %REGULATORY_CUSTOM_REG,
154 * %REGULATORY_STRICT_REG, %REGULATORY_COUNTRY_IE_FOLLOW_POWER,
155 * %REGULATORY_COUNTRY_IE_IGNORE and %REGULATORY_DISABLE_BEACON_HINTS.
156 * Mixing any of the above flags with this flag will result in a failure
157 * to register the wiphy. This flag implies
158 * %REGULATORY_DISABLE_BEACON_HINTS and %REGULATORY_COUNTRY_IE_IGNORE.
