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.

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.

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 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).
62
63
64config CFG80211_REG_DEBUG
65	bool "cfg80211 regulatory debugging"
66	depends on CFG80211
67	default n
68	---help---
69	  You can enable this if you want to debug regulatory changes.
70	  For more information on cfg80211 regulatory refer to the wireless
71	  wiki:
72
73	  http://wireless.kernel.org/en/developers/Regulatory
74
75	  If unsure, say N.
76
77config CFG80211_CERTIFICATION_ONUS
78	bool "cfg80211 certification onus"
79	depends on CFG80211 && EXPERT
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
98config 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
111config 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
135config CFG80211_DEFAULT_PS
136	bool "enable powersave by default"
137	depends on CFG80211
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.
145
146config CFG80211_DEBUGFS
147	bool "cfg80211 DebugFS entries"
148	depends on CFG80211
149	depends on DEBUG_FS
150	---help---
151	  You can enable this if you want to debugfs entries for cfg80211.
152
153	  If unsure, say N.
154
155config CFG80211_INTERNAL_REGDB
156	bool "use statically compiled regulatory rules database" if EXPERT
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.
170
171	  For details see:
172
173	  http://wireless.kernel.org/en/developers/Regulatory
174
175	  Most distributions have a CRDA package.  So if unsure, say N.

185
186config CFG80211_WEXT_EXPORT
