  54           cfg80211 developers and driver developers, but beware that
  55           they can also trigger due to races with userspace.
  56
  57           For example, when a driver reports that it was disconnected
  58           from the AP, but the user disconnects manually at the same
  59           time, the warning might trigger spuriously due to races.

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

 120           This option enables support for parsing regulatory hints
 121           from cellular base stations. If enabled and at least one driver
 122           claims support for parsing cellular base station hints the
 123           regulatory core will allow and parse these regulatory hints.
 124           The regulatory core will only apply these regulatory hints on
 125           drivers that support this feature. You should only enable this
 126           feature if you have tested and validated this feature on your

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

 160           If this causes your applications to misbehave you should fix your
