ieee80211_sta_eosp(9) [centos man page]

IEEE80211_STA_EOSP(9)					     Advanced driver interface					     IEEE80211_STA_EOSP(9)

NAME
ieee80211_sta_eosp - notify mac80211 about end of SP SYNOPSIS
void ieee80211_sta_eosp(struct ieee80211_sta * pubsta); ARGUMENTS
pubsta the station DESCRIPTION
When a device transmits frames in a way that it can't tell mac80211 in the TX status about the EOSP, it must clear the IEEE80211_TX_STATUS_EOSP bit and call this function instead. This applies for PS-Poll as well as uAPSD. Note that just like with _tx_status and _rx drivers must not mix calls to irqsafe/non-irqsafe versions, this function must not be mixed with those either. Use the all irqsafe, or all non-irqsafe, don't mix! NB
the _irqsafe version of this function doesn't exist, no driver needs it right now. Don't call this function if you'd need the _irqsafe version, look at the git history and restore the _irqsafe version! AUTHOR

NAME
ieee80211_sta_set_buffered - inform mac80211 about driver-buffered frames SYNOPSIS
void ieee80211_sta_set_buffered(struct ieee80211_sta * sta, u8 tid, bool buffered); ARGUMENTS
sta struct ieee80211_sta pointer for the sleeping station tid the TID that has buffered frames buffered indicates whether or not frames are buffered for this TID DESCRIPTION
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.
