   when tested with hwsim, like skip CAC abort event when radar
   detected, or clearing lower level bgCAC correctly
2) Set CAC ongoing, so user mode don't have to guess if CAC ongoing
   For this one also have iw patch that will extend iw phyX channels
3) For test purpose extend mac80211_hwsim and report bgCAC support
