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

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

52 This option enables some additional warnings that help
Ola Olsson573a2b52016-01-10 18:41:42 +010053 cfg80211 developers and driver developers, but beware that
54 they can also trigger due to races with userspace.
Johannes Bergf7969962009-08-21 12:23:49 +020055
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).

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.

91 claims support for parsing cellular base station hints the
92 regulatory core will allow and parse these regulatory hints.

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.

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
Ola Olsson573a2b52016-01-10 18:41:42 +0100113 scenarios, this relaxation is not allowed in cases where the BSS client
Ilan Peer174e0cd2014-02-23 09:13:01 +0200114 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.

147 This option generates an internal data structure representing
148 the wireless regulatory rules described in net/wireless/db.txt
Ola Olsson573a2b52016-01-10 18:41:42 +0100149 and includes code to query that database. This is an alternative
John W. Linville3b377ea2009-12-18 17:59:01 -0500150 to using CRDA for defining regulatory rules for the kernel.
151
Luis R. Rodriguezfa96aab2014-07-14 14:19:49 -0700152 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
