flags

configuration flags defined above

power_level

requested transmit power (in dBm), backward compatibility value only that is set to the minimum of all interfaces

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

chandef

the channel definition to tune to

radar_enabled

whether radar detection is enabled

smps_mode

spatial multiplexing powersave mode; note that IEEE80211_SMPS_STATIC is used when the device is not configured for an HT channel. Note that this is only valid if channel contexts are not used, otherwise each channel context has the number of chains listed.

This struct indicates how the driver shall configure the hardware.
