  23           cfg80211 is the Linux wireless LAN (802.11) configuration API.

  37           factory calibration or validation tools for wireless chips.

  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).

  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

  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
 111 config 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

 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.

 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.
