	 IEEE80211_CHAN_DISABLED,
	 IEEE80211_CHAN_PASSIVE_SCAN,
	 IEEE80211_CHAN_NO_IBSS,
	 IEEE80211_CHAN_RADAR,
	 IEEE80211_CHAN_NO_HT40PLUS,
	 IEEE80211_CHAN_NO_HT40MINUS,
	 IEEE80211_CHAN_NO_OFDM,

       };

CONSTANTS
       IEEE80211_CHAN_DISABLED
	   This channel is disabled.

       IEEE80211_CHAN_PASSIVE_SCAN
	   Only passive scanning is permitted on this channel.

       IEEE80211_CHAN_NO_IBSS
	   IBSS is not allowed on this channel.

       IEEE80211_CHAN_RADAR
	   Radar detection is required on this channel.

       IEEE80211_CHAN_NO_HT40PLUS
	   extension channel above this channel is not permitted.

       IEEE80211_CHAN_NO_HT40MINUS
	   extension channel below this channel is not permitted.

       IEEE80211_CHAN_NO_OFDM
	   OFDM is not allowed on this channel.

       IEEE80211_CHAN_NO_80MHZ
	   If the driver supports 80 MHz on the band, this flag indicates that an 80 MHz channel cannot use this channel as the control or any of
	   the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions.

       IEEE80211_CHAN_NO_160MHZ
	   If the driver supports 160 MHz on the band, this flag indicates that an 160 MHz channel cannot use this channel as the control or any
	   of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions.

DESCRIPTION
       Channel flags set by the regulatory control code.
