21	depends on RFKILL || !RFKILL
22	---help---
23	  cfg80211 is the Linux wireless LAN (802.11) configuration API.
24	  Enable this if you have a wireless device.
25
26	  For more information refer to documentation on the wireless wiki:
27
28	  http://wireless.kernel.org/en/developers/Documentation/cfg80211
29
30	  When built as a module it will be called cfg80211.
31
32config NL80211_TESTMODE
33	bool "nl80211 testmode command"
34	depends on CFG80211
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.
44
45	  Say N.
46
47config CFG80211_DEVELOPER_WARNINGS
48	bool "enable developer warnings"
49	depends on CFG80211
50	default n
51	help
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.
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).
62
63
64config CFG80211_CERTIFICATION_ONUS
65	bool "cfg80211 certification onus"
66	depends on CFG80211 && EXPERT
67	default n
68	---help---
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
76	  in place.
77
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.
84
85config CFG80211_REG_CELLULAR_HINTS
86	bool "cfg80211 regulatory support for cellular base station hints"
87	depends on CFG80211_CERTIFICATION_ONUS
88	---help---
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
96	  systems.
97
98config CFG80211_REG_RELAX_NO_IR
99	bool "cfg80211 support for NO_IR relaxation"
100	depends on CFG80211_CERTIFICATION_ONUS
101	---help---
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.
107
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
116	 non P2P clients.
117
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.
121
122config CFG80211_DEFAULT_PS
123	bool "enable powersave by default"
124	depends on CFG80211
125	default y
126	help
127	  This option enables powersave mode by default.
128
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.
132
133config CFG80211_DEBUGFS
134	bool "cfg80211 DebugFS entries"
135	depends on CFG80211
136	depends on DEBUG_FS
137	---help---
138	  You can enable this if you want debugfs entries for cfg80211.
139
140	  If unsure, say N.
141
142config CFG80211_INTERNAL_REGDB
143	bool "use statically compiled regulatory rules database" if EXPERT
144	default n
145	depends on CFG80211
146	---help---
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.
151
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
156	  wireless-regdb.
157
158	  For details see:
159
160	  http://wireless.kernel.org/en/developers/Regulatory
161
162	  Most distributions have a CRDA package. So if unsure, say N.
163
164config CFG80211_CRDA_SUPPORT
165	bool "support CRDA" if CFG80211_INTERNAL_REGDB
166	default y
167	depends on CFG80211
168	help
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.)
171
172	  If unsure, say Y.
173
174config CFG80211_WEXT
175	bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT
176	depends on CFG80211
177	select WEXT_CORE
178	default y if CFG80211_WEXT_EXPORT
179	help
180	  Enable this option if you need old userspace for wireless
181	  extensions with cfg80211-based drivers.
182
183config CFG80211_WEXT_EXPORT
184	bool
185	depends on CFG80211
186	help
187	  Drivers should select this option if they require cfg80211's
188	  wext compatibility symbols to be exported.
189
190config LIB80211
191	tristate
192	default n
193	help
194	  This options enables a library of common routines used
195	  by IEEE802.11 wireless LAN drivers.
196
197	  Drivers should select this themselves if needed.

213	  You can enable this if you want verbose debugging messages
214	  from lib80211.
215
216	  If unsure, say N.
