+ This option enables support for parsing regulatory hints
+ from cellular base stations. If enabled and at least one driver
+ claims support for parsing cellular base station hints the

+ The regulatory core will only apply these regulatory hints on

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