39  * @interference_thresh_teardown: Minimum interference above that TWT
40  *                 will not be active. The interference parameters use an
41  *                 abstract method of evaluating interference.
42  *                 The parameters are in percent, ranging from 0 for no
43  *                 interference, to 100 for interference extreme enough
44  *                 to completely block the signal of interest.
45  * @interference_thresh_setup: Minimum interference below that TWT session
46  *                 can be setup. The interference parameters use an
47  *                 abstract method of evaluating interference.

49  *                 interference, to 100 for interference extreme enough
50  *                 to completely block the signal of interest.
51  * @min_no_sta_setup: Minimum no of STA required to start TWT setup
52  * @min_no_sta_teardown: Minimum no of STA below which TWT will be torn down
53  * @no_of_bcast_mcast_slots: Number of default slot sizes reserved for
54  *                 BCAST/MCAST delivery
55  * @min_no_twt_slots: Minimum no of available slots for TWT to be operational
56  * @max_no_sta_twt: Max no of STA with which TWT is possible
57  *                 (must be <= the wmi_resource_config's twt_ap_sta_count value)
58  *      * The below interval parameters have units of milliseconds.
59  * @mode_check_interval: Interval between two successive check to decide the
60  *                 mode of TWT. (units = milliseconds)
61  * @add_sta_slot_interval: Interval between decisions making to create
62  *                 TWT slots for STAs. (units = milliseconds)
63  * @remove_sta_slot_interval: Inrerval between decisions making to remove TWT
64  *                 slot of STAs. (units = milliseconds)
