IEEE80211_STA_SET_BU(9) Advanced driver interface IEEE80211_STA_SET_BU(9)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.

IEEE80211_STA_BLOCK_(9) Advanced driver interface IEEE80211_STA_BLOCK_(9)NAME
ieee80211_sta_block_awake - block station from waking up
SYNOPSIS
void ieee80211_sta_block_awake(struct ieee80211_hw * hw, struct ieee80211_sta * pubsta, bool block);
ARGUMENTS
hw
the hardware
pubsta
the station
block
whether to block or unblock
DESCRIPTION
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.

The problem is that I use this station as a remote computer for an AOI Orbotech machine and in the root of the station there is no memory available and on the refmgr folder on the same station there are 5GB free memory. So if anyone knows how can I free some space and not damaging the root files,... (0 Replies)
