IEEE80211_SCAN_COMPL(9) Advanced driver interface IEEE80211_SCAN_COMPL(9)NAME
ieee80211_scan_completed - completed hardware scan
void ieee80211_scan_completed(struct ieee80211_hw * hw, bool aborted);
the hardware that finished the scan
set to true if scan was aborted
When hardware scan offload is used (i.e. the hw_scan callback is assigned) this function needs to be called by the driver to notify
mac80211 that the scan finished. This function can be called from any context, including hardirq context.

ieee80211_sta_set_buffered - inform mac80211 about driver-buffered frames
void ieee80211_sta_set_buffered(struct ieee80211_sta * sta, u8 tid, bool buffered);
struct ieee80211_sta pointer for the sleeping station
the TID that has buffered frames
indicates whether or not frames are buffered for this TID
If a driver buffers frames for a powersave station instead of passing them back to mac80211 for retransmission, the station may still need
to be told that there are buffered frames via the TIM bit.
This function informs mac80211 whether or not there are frames that are buffered in the driver for a given TID; mac80211 can then use this
data to set the TIM bit (NOTE: This may call back into the driver's set_tim call! Beware of the locking!)
If all frames are released to the station (due to PS-poll or uAPSD) then the driver needs to inform mac80211 that there no longer are
frames buffered. However, when the station wakes up mac80211 assumes that all buffered frames will be transmitted and clears this data,
drivers need to make sure they inform mac80211 about all buffered frames on the sleep transition (sta_notify with STA_NOTIFY_SLEEP).
Note that technically mac80211 only needs to know this per AC, not per TID, but since driver buffering will inevitably happen per TID
(since it is related to aggregation) it is easier to make mac80211 map the TID to the AC as required instead of keeping track in all
drivers that use this API.
