STRUCT 
IEEE80211_CHA(9) 					Device registration					   STRUCT IEEE80211_CHA(9)

NAME

       struct_ieee80211_channel - channel definition

SYNOPSIS

       struct ieee80211_channel {
	 enum ieee80211_band band;
	 u16 center_freq;
	 u16 hw_value;
	 u32 flags;
	 int max_antenna_gain;
	 int max_power;
	 int max_reg_power;
	 bool beacon_found;
	 u32 orig_flags;
	 int orig_mag;
	 int orig_mpwr;
	 enum nl80211_dfs_state dfs_state;
	 unsigned long dfs_state_entered;
       };

MEMBERS

       band
	   band this channel belongs to.

       center_freq
	   center frequency in MHz

       hw_value
	   hardware-specific value for the channel

       flags
	   channel flags from enum ieee80211_channel_flags.

       max_antenna_gain
	   maximum antenna gain in dBi

       max_power
	   maximum transmission power (in dBm)

       max_reg_power
	   maximum regulatory transmission power (in dBm)

       beacon_found
	   helper to regulatory code to indicate when a beacon has been found on this channel. Use regulatory_hint_found_beacon to enable this,
	   this is useful only on 5 GHz band.

       orig_flags
	   channel flags at registration time, used by regulatory code to support devices with additional restrictions

       orig_mag
	   internal use

       orig_mpwr
	   internal use

       dfs_state
	   current state of this channel. Only relevant if radar is required on this channel.

       dfs_state_entered
	   timestamp (jiffies) when the dfs state was entered.

DESCRIPTION

       This structure describes a single channel for use with cfg80211.

NAME

       struct_ieee80211_conf - configuration of the device

SYNOPSIS

       struct ieee80211_conf {
	 u32 flags;
	 int power_level;
	 int dynamic_ps_timeout;
	 int max_sleep_period;
	 u16 listen_interval;
	 u8 ps_dtim_period;
	 u8 long_frame_max_tx_count;
	 u8 short_frame_max_tx_count;
	 struct ieee80211_channel * channel;
	 enum nl80211_channel_type channel_type;
	 enum ieee80211_smps_mode smps_mode;
       };

MEMBERS

       flags
	   configuration flags defined above

       power_level
	   requested transmit power (in dBm)

       dynamic_ps_timeout
	   The dynamic powersave timeout (in ms), see the powersave documentation below. This variable is valid only when the CONF_PS flag is set.

       max_sleep_period
	   the maximum number of beacon intervals to sleep for before checking the beacon for a TIM bit (managed mode only); this value will be
	   only achievable between DTIM frames, the hardware needs to check for the multicast traffic bit in DTIM beacons. This variable is valid
	   only when the CONF_PS flag is set.

       listen_interval
	   listen interval in units of beacon interval

       ps_dtim_period
	   The DTIM period of the AP we're connected to, for use in power saving. Power saving will not be enabled until a beacon has been
	   received and the DTIM period is known.

       long_frame_max_tx_count
	   Maximum number of transmissions for a "long" frame (a frame not RTS protected), called "dot11LongRetryLimit" in 802.11, but actually
	   means the number of transmissions not the number of retries

       short_frame_max_tx_count
	   Maximum number of transmissions for a "short" frame, called "dot11ShortRetryLimit" in 802.11, but actually means the number of
	   transmissions not the number of retries

       channel
	   the channel to tune to

       channel_type
	   the channel (HT) type

       smps_mode
	   spatial multiplexing powersave mode; note that IEEE80211_SMPS_STATIC is used when the device is not configured for an HT channel

DESCRIPTION

       This struct indicates how the driver shall configure the hardware.
