+ from DT
 MIME-Version: 1.0
 Content-Type: text/plain; charset=UTF-8
 Content-Transfer-Encoding: 8bit
 
+This new helper reads extra frequency limits specified in DT and
+disables unavailable chanels. This is useful for devices (like home
+routers) with chipsets limited e.g. by board design.
+
+In order to respect info read from DT we simply need to check for
+IEEE80211_CHAN_DISABLED bit when constructing channel info.
