-Subject: [PATCH 26/26] cfg80211: add cellular base station regulatory hint
- support
-
-Cellular base stations can provide hints to cfg80211 about
-where they think we are. This can be done for example by on
-a cell phone. To enable these hints we simply allow them
-through as user regulatory hints but we allow userspace
-to clasify the hint. This option is only available for
-system integrators which are willing to enable
-CONFIG_CFG80211_CERTIFICATION_ONUS.
