29	  cfg80211 is the Linux wireless LAN (802.11) configuration API.
30	  Enable this if you have a wireless device.
31
32	  For more information refer to documentation on the wireless wiki:
33
34	  http://wireless.kernel.org/en/developers/Documentation/cfg80211
35
36	  When built as a module it will be called cfg80211.

45

58	  This option enables some additional warnings that help
59	  cfg80211 developers and driver developers, but beware that
60	  they can also trigger due to races with userspace.
61
62	  For example, when a driver reports that it was disconnected
63	  from the AP, but the user disconnects manually at the same
64	  time, the warning might trigger spuriously due to races.
65
66	  Say Y only if you are developing cfg80211 or a driver based
67	  on it (or mac80211).

75	  You should disable this option unless you are both capable
76	  and willing to ensure your system will remain regulatory
77	  compliant with the features available under this option.
78	  Some options may still be under heavy development and
79	  for whatever reason regulatory compliance has not or
80	  cannot yet be verified. Regulatory verification may at
81	  times only be possible until you have the final system
82	  in place.
83
84	  This option should only be enabled by system integrators
85	  or distributions that have done work necessary to ensure
86	  regulatory certification on the system with the enabled
87	  features. Alternatively you can enable this option if
88	  you are a wireless researcher and are working in a controlled
89	  and approved environment by your local regulatory agency.

127	---help---
128	  This option enables support for parsing regulatory hints
129	  from cellular base stations. If enabled and at least one driver
130	  claims support for parsing cellular base station hints the
131	  regulatory core will allow and parse these regulatory hints.
132	  The regulatory core will only apply these regulatory hints on
133	  drivers that support this feature. You should only enable this
134	  feature if you have tested and validated this feature on your
135	  systems.

137config CFG80211_REG_RELAX_NO_IR
138	bool "cfg80211 support for NO_IR relaxation"
139	depends on CFG80211_CERTIFICATION_ONUS
140	---help---
141	 This option enables support for relaxation of the NO_IR flag for
142	 situations that certain regulatory bodies have provided clarifications
143	 on how relaxation can occur. This feature has an inherent dependency on
144	 userspace features which must have been properly tested and as such is
145	 not enabled by default.
146
147	 A relaxation feature example is allowing the operation of a P2P group
148	 owner (GO) on channels marked with NO_IR if there is an additional BSS
149	 interface which associated to an AP which userspace assumes or confirms
150	 to be an authorized master, i.e., with radar detection support and DFS
151	 capabilities. However, note that in order to not create daisy chain
152	 scenarios, this relaxation is not allowed in cases where the BSS client
153	 is associated to P2P GO and in addition the P2P GO instantiated on
154	 a channel due to this relaxation should not allow connection from
155	 non P2P clients.
156
157	 The regulatory core will apply these relaxations only for drivers that
158	 support this feature by declaring the appropriate channel flags and
159	 capabilities in their registration flow.

166
167	  If this causes your applications to misbehave you should fix your

169	  latency requirement, see Documentation/power/pm_qos_interface.rst.
