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

  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

  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

 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.

 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.

 166
 167           If this causes your applications to misbehave you should fix your
 168           applications instead -- they need to register their network
 169           latency requirement, see Documentation/power/pm_qos_interface.txt.
