 23           cfg80211 is the Linux wireless LAN (802.11) configuration API.
 24           Enable this if you have a wireless device.

 26           For more information refer to documentation on the wireless wiki:

 35         help
 36           The nl80211 testmode command helps implementing things like
 37           factory calibration or validation tools for wireless chips.
 38 
 39           Select this option ONLY for kernels that are specifically
 40           built for such purposes.
 41 
 42           Debugging tools that are supposed to end up in the hands of
 43           users should better be implemented with debugfs.

 51         help
 52           This option enables some additional warnings that help
 53           cfg80211 developers and driver developers, but that can
 54           trigger due to races with userspace.
 55 
 56           For example, when a driver reports that it was disconnected
 57           from the AP, but the user disconnects manually at the same
 58           time, the warning might trigger spuriously due to races.
 59 
 60           Say Y only if you are developing cfg80211 or a driver based
 61           on it (or mac80211).

 80         default n
 81         ---help---
 82           You should disable this option unless you are both capable
 83           and willing to ensure your system will remain regulatory
 84           compliant with the features available under this option.
 85           Some options may still be under heavy development and
 86           for whatever reason regulatory compliance has not or
 87           cannot yet be verified. 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 
 98 config 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. You should only enable this
108           feature if you have tested and validated this feature on your
109           systems.
110 
111 config CFG80211_REG_RELAX_NO_IR
112         bool "cfg80211 support for NO_IR relaxation"
113         depends on CFG80211_CERTIFICATION_ONUS
114         ---help---
115          This option enables support for relaxation of the NO_IR flag for
116          situations that certain regulatory bodies have provided clarifications
117          on how relaxation can occur. 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 
135 config CFG80211_DEFAULT_PS

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.

149         depends on DEBUG_FS
150         ---help---
151           You can enable this if you want to debugfs entries for cfg80211.

154

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.
