IEEE80211_ITERATE_AC(9) Advanced driver interface IEEE80211_ITERATE_AC(9)NAME
ieee80211_iterate_active_interfaces_atomic - iterate active interfaces
void ieee80211_iterate_active_interfaces_atomic(struct ieee80211_hw * hw, u32 iter_flags,
void (*iterator) (void *data, u8 *mac, struct ieee80211_vif *vif), void * data);
the hardware struct of which the interfaces should be iterated over
iteration flags, see enum ieee80211_interface_iteration_flags
the iterator function to call, cannot sleep
first argument of the iterator function
This function iterates over the interfaces associated with a given hardware that are currently active and calls the callback for them. This
function requires the iterator callback function to be atomic, if that is not desired, use ieee80211_iterate_active_interfaces instead.
Does not iterate over a new interface during add_interface.

IEEE80211_STA_BLOCK_(9) Advanced driver interface IEEE80211_STA_BLOCK_(9)NAME
ieee80211_sta_block_awake - block station from waking up
void ieee80211_sta_block_awake(struct ieee80211_hw * hw, struct ieee80211_sta * pubsta, bool block);
whether to block or unblock
Some devices require that all frames that are on the queues for a specific station that went to sleep are flushed before a poll response or
frames after the station woke up can be delivered to that it. Note that such frames must be rejected by the driver as filtered, with the
appropriate status flag.
This function allows implementing this mode in a race-free manner.
To do this, a driver must keep track of the number of frames still enqueued for a specific station. If this number is not zero when the
station goes to sleep, the driver must call this function to force mac80211 to consider the station to be asleep regardless of the
station's actual state. Once the number of outstanding frames reaches zero, the driver must call this function again to unblock the
station. That will cause mac80211 to be able to send ps-poll responses, and if the station queried in the meantime then frames will also be
sent out as a result of this. Additionally, the driver will be notified that the station woke up some time after it is unblocked,
regardless of whether the station actually woke up while blocked or not.
