30 cfg80211 is the Linux wireless LAN (802.11) configuration API.
31 Enable this if you have a wireless device.
32
33 For more information refer to documentation on the wireless wiki:
34
35 https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211

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

45 factory calibration or validation tools for wireless chips.
46

48 built for such purposes.

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

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

119 certificates like in the kernel sources (net/wireless/certs/)
120 that shall be accepted for a signed regulatory database.
121
122 Note that you need to also select the correct CRYPTO_<hash> modules
123 for your certificates, and if cfg80211 is built-in they also must be.

125config CFG80211_REG_CELLULAR_HINTS
126 bool "cfg80211 regulatory support for cellular base station hints"
127 depends on CFG80211_CERTIFICATION_ONUS
128 help
129 This option enables support for parsing regulatory hints
130 from cellular base stations. If enabled and at least one driver
131 claims support for parsing cellular base station hints the
132 regulatory core will allow and parse these regulatory hints.
133 The regulatory core will only apply these regulatory hints on
134 drivers that support this feature. You should only enable this
135 feature if you have tested and validated this feature on your
136 systems.

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