28 cfg80211 is the Linux wireless LAN (802.11) configuration API.
29 Enable this if you have a wireless device.

31 For more information refer to documentation on the wireless wiki:

33 http://wireless.kernel.org/en/developers/Documentation/cfg80211

35 When built as a module it will be called cfg80211.

42 factory calibration or validation tools for wireless chips.
43
44 Select this option ONLY for kernels that are specifically
45 built for such purposes.

47 Debugging tools that are supposed to end up in the hands of
48 users should better be implemented with debugfs.

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

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

120 Note that you need to also select the correct CRYPTO_<hash> modules
121 for your certificates, and if cfg80211 is built-in they also must be.

125 depends on CFG80211_CERTIFICATION_ONUS
126 ---help---
127 This option enables support for parsing regulatory hints
128 from cellular base stations. If enabled and at least one driver
129 claims support for parsing cellular base station hints the
130 regulatory core will allow and parse these regulatory hints.
131 The regulatory core will only apply these regulatory hints on
132 drivers that support this feature. You should only enable this
133 feature if you have tested and validated this feature on your
134 systems.

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