If enabled and at least one driver 122 claims support for parsing cellular base station hints the 123 regulatory core will allow and parse these regulatory hints. 124 The regulatory core will only apply these regulatory hints on 125 drivers that support this feature.

This feature has an inherent dependency on 136 userspace features which must have been properly tested and as such is 137 not enabled by default. 138 139 A relaxation feature example is allowing the operation of a P2P group 140 owner (GO) on channels marked with NO_IR if there is an additional BSS 141 interface which associated to an AP which userspace assumes or confirms 142 to be an authorized master, i.e., with radar detection support and DFS 143 capabilities. However, note that in order to not create daisy chain 144 scenarios, this relaxation is not allowed in cases where the BSS client 145 is associated to P2P GO and in addition the P2P GO instantiated on 146 a channel due to this relaxation should not allow connection from 147 non P2P clients. 148 149 The regulatory core will apply these relaxations only for drivers that 150 support this feature by declaring the appropriate channel flags and 151 capabilities in their registration flow. 152 153config CFG80211_DEFAULT_PS 154 bool "enable powersave by default" 155 depends on CFG80211 156 default y 157 help 158 This option enables powersave mode by default. 159 160 If this causes your applications to misbehave you should fix your 161 applications instead -- they need to register their network 162 latency requirement, see Documentation/power/pm_qos_interface.txt. 163 164config CFG80211_DEBUGFS 165 bool "cfg80211 DebugFS entries" 166 depends on CFG80211 167 depends on DEBUG_FS 168 ---help--- 169 You can enable this if you want debugfs entries for cfg80211. 170 171 If unsure, say N. 172 173config CFG80211_CRDA_SUPPORT 174 bool "support CRDA" if EXPERT 175 default y 176 depends on CFG80211 177 help 178 You should enable this option unless you know for sure you have no 179 need for it, for example when using internal regdb (above) or the 180 database loaded as a firmware file. 181 182 If unsure, say Y. 183 184config CFG80211_WEXT 185 bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT 186 depends on CFG80211 187 select WEXT_CORE 188 default y if CFG80211_WEXT_EXPORT 189 help 190 Enable this option if you need old userspace for wireless 191 extensions with cfg80211-based drivers. 192 193config CFG80211_WEXT_EXPORT 194 bool 195 depends on CFG80211 196 help 197 Drivers should select this option if they require cfg80211's 198 wext compatibility symbols to be exported. 199 200config LIB80211 201 tristate 202 default n 203 help 204 This options enables a library of common routines used 205 by IEEE802.11 wireless LAN drivers. 206 207 Drivers should select this themselves if needed. 208 209config LIB80211_CRYPT_WEP 210 tristate 211 212config LIB80211_CRYPT_CCMP 213 tristate 214 215config LIB80211_CRYPT_TKIP 216 tristate 217 218config LIB80211_DEBUG 219 bool "lib80211 debugging messages" 220 depends on LIB80211 221 default n 222 ---help--- 223 You can enable this if you want verbose debugging messages 224 from lib80211. 225 226 If unsure, say N. 227
