24 cfg80211 is the Linux wireless LAN (802.11) configuration API.
25 Enable this if you have a wireless device.
27 For more information refer to documentation on the wireless wiki:
29 http://wireless.kernel.org/en/developers/Documentation/cfg80211
31 When built as a module it will be called cfg80211.
33 config NL80211_TESTMODE
34 bool "nl80211 testmode command"
37 The nl80211 testmode command helps implementing things like
38 factory calibration or validation tools for wireless chips.
40 Select this option ONLY for kernels that are specifically
41 built for such purposes.
43 Debugging tools that are supposed to end up in the hands of
44 users should better be implemented with debugfs.
48 config CFG80211_DEVELOPER_WARNINGS
49 bool "enable developer warnings"
53 This option enables some additional warnings that help
54 cfg80211 developers and driver developers, but beware that
55 they can also trigger due to races with userspace.
57 For example, when a driver reports that it was disconnected
58 from the AP, but the user disconnects manually at the same
59 time, the warning might trigger spuriously due to races.

65 config CFG80211_CERTIFICATION_ONUS
66 bool "cfg80211 certification onus"
67 depends on CFG80211 && EXPERT
70 You should disable this option unless you are both capable
71 and willing to ensure your system will remain regulatory
72 compliant with the features available under this option.
73 Some options may still be under heavy development and
74 for whatever reason regulatory compliance has not or
75 cannot yet be verified. Regulatory verification may at
76 times only be possible until you have the final system
79 This option should only be enabled by system integrators
80 or distributions that have done work necessary to ensure
81 regulatory certification on the system with the enabled
82 features. Alternatively you can enable this option if
83 you are a wireless researcher and are working in a controlled
84 and approved environment by your local regulatory agency.

87 bool "require regdb signature" if CFG80211_CERTIFICATION_ONUS
89 select SYSTEM_DATA_VERIFICATION
91 Require that in addition to the "regulatory.db" file a

112 If selected, point to a directory with DER-encoded X.509
113 certificates like in the kernel sources (net/wireless/certs/)
114 that shall be accepted for a signed regulatory database.
116 config CFG80211_REG_CELLULAR_HINTS
117 bool "cfg80211 regulatory support for cellular base station hints"
118 depends on CFG80211_CERTIFICATION_ONUS
120 This option enables support for parsing regulatory hints
121 from cellular base stations. 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. You should only enable this
126 feature if you have tested and validated this feature on your
129 config CFG80211_REG_RELAX_NO_IR
130 bool "cfg80211 support for NO_IR relaxation"
131 depends on CFG80211_CERTIFICATION_ONUS
133 This option enables support for relaxation of the NO_IR flag for
134 situations that certain regulatory bodies have provided clarifications
135 on how relaxation can occur. 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.
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
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.
153 config CFG80211_DEFAULT_PS
154 bool "enable powersave by default"
158 This option enables powersave mode by default.
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.
164 config CFG80211_DEBUGFS
165 bool "cfg80211 DebugFS entries"
169 You can enable this if you want debugfs entries for cfg80211.
173 config CFG80211_CRDA_SUPPORT
174 bool "support CRDA" if EXPERT
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.
185 bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT
188 default y if CFG80211_WEXT_EXPORT
190 Enable this option if you need old userspace for wireless
191 extensions with cfg80211-based drivers.
193 config CFG80211_WEXT_EXPORT
197 Drivers should select this option if they require cfg80211's
198 wext compatibility symbols to be exported.
204 This options enables a library of common routines used
205 by IEEE802.11 wireless LAN drivers.
207 Drivers should select this themselves if needed.
