Regulatory verification may at 88 times only be possible until you have the final system 89 in place. 90 91 This option should only be enabled by system integrators 92 or distributions that have done work necessary to ensure 93 regulatory certification on the system with the enabled 94 features. Alternatively you can enable this option if 95 you are a wireless researcher and are working in a controlled 96 and approved environment by your local regulatory agency. 97 98config CFG80211_REG_CELLULAR_HINTS 99 bool "cfg80211 regulatory support for cellular base station hints" 100 depends on CFG80211_CERTIFICATION_ONUS 101 ---help--- 102 This option enables support for parsing regulatory hints 103 from cellular base stations. If enabled and at least one driver 104 claims support for parsing cellular base station hints the 105 regulatory core will allow and parse these regulatory hints. 106 The regulatory core will only apply these regulatory hints on 107 drivers that support this feature.

This feature has an inherent dependency on 118 userspace features which must have been properly tested and as such is 119 not enabled by default. 120 121 A relaxation feature example is allowing the operation of a P2P group 122 owner (GO) on channels marked with NO_IR if there is an additional BSS 123 interface which associated to an AP which userspace assumes or confirms 124 to be an authorized master, i.e., with radar detection support and DFS 125 capabilities. However, note that in order to not create daisy chain 126 scenarios, this relaxation is not allowed in cases that the BSS client 127 is associated to P2P GO and in addition the P2P GO instantiated on 128 a channel due to this relaxation should not allow connection from 129 non P2P clients. 130 131 The regulatory core will apply these relaxations only for drivers that 132 support this feature by declaring the appropriate channel flags and 133 capabilities in their registration flow. 134 135config CFG80211_DEFAULT_PS 136 bool "enable powersave by default" 137 depends on CFG80211 138 default y 139 help 140 This option enables powersave mode by default. 141 142 If this causes your applications to misbehave you should fix your 143 applications instead -- they need to register their network 144 latency requirement, see Documentation/power/pm_qos_interface.txt. 145 146config CFG80211_DEBUGFS 147 bool "cfg80211 DebugFS entries" 148 depends on CFG80211 149 depends on DEBUG_FS 150 ---help--- 151 You can enable this if you want to debugfs entries for cfg80211. 152 153 If unsure, say N. 154 155config CFG80211_INTERNAL_REGDB 156 bool "use statically compiled regulatory rules database" if EXPERT 157 default n 158 depends on CFG80211 159 ---help--- 160 This option generates an internal data structure representing 161 the wireless regulatory rules described in net/wireless/db.txt 162 and includes code to query that database. This is an alternative 163 to using CRDA for defining regulatory rules for the kernel. 164 165 Using this option requires some parsing of the db.txt at build time, 166 the parser will be upkept with the latest wireless-regdb updates but 167 older wireless-regdb formats will be ignored. The parser may later 168 be replaced to avoid issues with conflicts on versions of 169 wireless-regdb. 170 171 For details see: 172 173 http://wireless.kernel.org/en/developers/Regulatory 174 175 Most distributions have a CRDA package.
