IEEE80211_STA_EOSP(9) Advanced driver interface IEEE80211_STA_EOSP(9)NAME
ieee80211_sta_eosp - notify mac80211 about end of SP
void ieee80211_sta_eosp(struct ieee80211_sta * pubsta);
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!
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!

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.
