486  *      not be forced to be sent to driver regardless of this delta. Typical
487  *      energy delta 5dB.

489  *      Send beacon to driver if delta in Energy values calculated for this
490  *      and last passed beacon is greater than this threshold. Zero value
491  *      means that the Energy change is ignored for beacon filtering while in

494  *      calculated for current beacon is less than the threshold, use
495  *      Roaming Energy Delta Threshold, otherwise use normal Energy Delta
496  *      Threshold. Typical energy threshold is -72dBm.

498  *	filtering (Slow or Fast) that is selected (Units are in Celsuis):
499  *	If the current temperature is above this threshold - Fast filter
500  *	will be used, If the current temperature is below this threshold -
501  *	Slow filter will be used.

503  *      calculated for this and the last passed beacon is greater than this
504  *      threshold. Zero value means that the temperature change is ignored for
505  *      beacon filtering; beacons will not be  forced to be sent to driver
506  *      regardless of whether its temerature has been changed.
507  * @bf_temp_slow_filter: Send Beacon to driver if delta in temperature values
508  *      calculated for this and the last passed beacon is greater than this
509  *      threshold. Zero value means that the temperature change is ignored for
510  *      beacon filtering; beacons will not be forced to be sent to driver
511  *      regardless of whether its temerature has been changed.
512  * @bf_enable_beacon_filter: 1, beacon filtering is enabled; 0, disabled.
513  * @bf_debug_flag: beacon filtering debug configuration
514  * @bf_escape_timer: Send beacons to to driver if no beacons were passed
515  *      for a specific period of time. Units: Beacons.
516  * @ba_escape_timer: Fully receive and parse beacon if no beacons were passed
517  *      for a longer period of time then this escape-timeout. Units: Beacons.
518  * @ba_enable_beacon_abort: 1, beacon abort is enabled; 0, disabled.

520  * @bf_threshold_absolute_high: Send Beacon to driver if Energy value calculated
521  *      for this beacon crossed this absolute threshold. For the 'Increase'
522  *      direction the bf_energy_absolute_low[i] is used. For the 'Decrease'
