SURVEY_INFO(9)					     Actions and configuration					     STRUCT SURVEY_INFO(9)

NAME

       struct_survey_info - channel survey response

SYNOPSIS

       struct survey_info {
	 struct ieee80211_channel * channel;
	 u64 channel_time;
	 u64 channel_time_busy;
	 u64 channel_time_ext_busy;
	 u64 channel_time_rx;
	 u64 channel_time_tx;
	 u32 filled;
	 s8 noise;
       };

MEMBERS

       channel
	   the channel this survey record reports, mandatory

       channel_time
	   amount of time in ms the radio spent on the channel

       channel_time_busy
	   amount of time the primary channel was sensed busy

       channel_time_ext_busy
	   amount of time the extension channel was sensed busy

       channel_time_rx
	   amount of time the radio spent receiving data

       channel_time_tx
	   amount of time the radio spent transmitting data

       filled
	   bitflag of flags from enum survey_info_flags

       noise
	   channel noise in dBm. This and all following fields are optional

DESCRIPTION

       Used by dump_survey to report back per-channel survey information.

       This structure can later be expanded with things like channel duty cycle etc.

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.
