20 tristate "cfg80211 - wireless configuration API"
21 depends on RFKILL || !RFKILL
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:
28 http://wireless.kernel.org/en/developers/Documentation/cfg80211
30 When built as a module it will be called cfg80211.
32 config NL80211_TESTMODE
33 bool "nl80211 testmode command"
36 The nl80211 testmode command helps implementing things like
37 factory calibration or validation tools for wireless chips.
39 Select this option ONLY for kernels that are specifically
40 built for such purposes.
42 Debugging tools that are supposed to end up in the hands of
43 users should better be implemented with debugfs.
47 config CFG80211_DEVELOPER_WARNINGS
48 bool "enable developer warnings"
52 This option enables some additional warnings that help
53 cfg80211 developers and driver developers, but beware that
54 they can also trigger due to races with userspace.
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.
60 Say Y only if you are developing cfg80211 or a driver based
64 config CFG80211_CERTIFICATION_ONUS
65 bool "cfg80211 certification onus"
66 depends on CFG80211 && EXPERT
69 You should disable this option unless you are both capable
70 and willing to ensure your system will remain regulatory
71 compliant with the features available under this option.
72 Some options may still be under heavy development and
73 for whatever reason regulatory compliance has not or
74 cannot yet be verified. Regulatory verification may at
75 times only be possible until you have the final system
78 This option should only be enabled by system integrators
79 or distributions that have done work necessary to ensure
80 regulatory certification on the system with the enabled
81 features. Alternatively you can enable this option if
82 you are a wireless researcher and are working in a controlled
83 and approved environment by your local regulatory agency.
85 config CFG80211_REG_CELLULAR_HINTS
86 bool "cfg80211 regulatory support for cellular base station hints"
87 depends on CFG80211_CERTIFICATION_ONUS
89 This option enables support for parsing regulatory hints
90 from cellular base stations. If enabled and at least one driver
91 claims support for parsing cellular base station hints the
92 regulatory core will allow and parse these regulatory hints.
93 The regulatory core will only apply these regulatory hints on
94 drivers that support this feature. You should only enable this
95 feature if you have tested and validated this feature on your
98 config CFG80211_REG_RELAX_NO_IR
99 bool "cfg80211 support for NO_IR relaxation"
100 depends on CFG80211_CERTIFICATION_ONUS
102 This option enables support for relaxation of the NO_IR flag for
103 situations that certain regulatory bodies have provided clarifications
104 on how relaxation can occur. This feature has an inherent dependency on
105 userspace features which must have been properly tested and as such is
106 not enabled by default.
108 A relaxation feature example is allowing the operation of a P2P group
109 owner (GO) on channels marked with NO_IR if there is an additional BSS
110 interface which associated to an AP which userspace assumes or confirms
111 to be an authorized master, i.e., with radar detection support and DFS
112 capabilities. However, note that in order to not create daisy chain
113 scenarios, this relaxation is not allowed in cases where the BSS client
114 is associated to P2P GO and in addition the P2P GO instantiated on
115 a channel due to this relaxation should not allow connection from
118 The regulatory core will apply these relaxations only for drivers that
119 support this feature by declaring the appropriate channel flags and
120 capabilities in their registration flow.
122 config CFG80211_DEFAULT_PS
123 bool "enable powersave by default"
127 This option enables powersave mode by default.
129 If this causes your applications to misbehave you should fix your
130 applications instead -- they need to register their network
131 latency requirement, see Documentation/power/pm_qos_interface.txt.
133 config CFG80211_DEBUGFS
134 bool "cfg80211 DebugFS entries"
138 You can enable this if you want debugfs entries for cfg80211.
142 config CFG80211_INTERNAL_REGDB
143 bool "use statically compiled regulatory rules database" if EXPERT
147 This option generates an internal data structure representing
148 the wireless regulatory rules described in net/wireless/db.txt
149 and includes code to query that database. This is an alternative
150 to using CRDA for defining regulatory rules for the kernel.
152 Using this option requires some parsing of the db.txt at build time,
153 the parser will be upkept with the latest wireless-regdb updates but
154 older wireless-regdb formats will be ignored. The parser may later
155 be replaced to avoid issues with conflicts on versions of
160 http://wireless.kernel.org/en/developers/Regulatory
162 Most distributions have a CRDA package. So if unsure, say N.
164 config CFG80211_CRDA_SUPPORT
165 bool "support CRDA" if CFG80211_INTERNAL_REGDB
169 You should enable this option unless you know for sure you have no
170 need for it, for example when using internal regdb (above.)
175 bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT
178 default y if CFG80211_WEXT_EXPORT
180 Enable this option if you need old userspace for wireless
181 extensions with cfg80211-based drivers.
183 config CFG80211_WEXT_EXPORT
187 Drivers should select this option if they require cfg80211's
188 wext compatibility symbols to be exported.
194 This options enables a library of common routines used
195 by IEEE802.11 wireless LAN drivers.
197 Drivers should select this themselves if needed.
199 config LIB80211_CRYPT_WEP
202 config LIB80211_CRYPT_CCMP
205 config LIB80211_CRYPT_TKIP
208 config LIB80211_DEBUG
209 bool "lib80211 debugging messages"
213 You can enable this if you want verbose debugging messages
