## CONSTANTS

IEEE80211\_CHAN\_DISABLED

This channel is disabled.

IEEE80211\_CHAN\_NO\_IR

do not initiate radiation, this includes sending probe requests or beaconing.

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.

IEEE80211\_CHAN\_INDOOR\_ONLY

see **NL80211\_FREQUENCY\_ATTR\_INDOOR\_ONLY**

IEEE80211\_CHAN\_GO\_CONCURRENT

see **NL80211\_FREQUENCY\_ATTR\_GO\_CONCURRENT**

IEEE80211\_CHAN\_NO\_20MHZ

20 MHz bandwidth is not permitted on this channel.

IEEE80211\_CHAN\_NO\_10MHZ

10 MHz bandwidth is not permitted on this channel.

## DESCRIPTION

Channel flags set by the regulatory control code.
