      iwlwifi: clean key table in iwl_clear_stations_table · 5e46882e
      Reinette Chatre authored
      
      
      Cleans uCode key table bit map iwl_clear_stations_table
      since all stations are cleared also the key table must be.
      
      Since the keys are not removed properly on suspend by mac80211
      this may result in exhausting key table on resume leading
      to memory corruption during removal
