/**
+ * DOC: AP support for powersaving clients
+ *
+ * In order to implement AP and P2P GO modes, mac80211 has support for
+ * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD.
+ * There currently is no support for sAPSD.
+ *
+ * There is one assumption that mac80211 makes, namely that a client
+ * will not poll with PS-Poll and trigger with uAPSD at the same time.
+ * Both are supported, and both can be used by the same client, but
+ * they can't be used concurrently by the same client. This simplifies
+ * the driver code.
+ *
+ * The first thing to keep in mind is that there is a flag for complete
+ * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set,
+ * mac80211 expects the driver to handle most of the state machine for
+ * powersaving clients and will ignore the PM bit in incoming frames.
+ * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of
+ * stations' powersave transitions. In this mode, mac80211 also doesn't
+ * handle PS-Poll/uAPSD.
+ *
+ * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the
+ * PM bit in incoming frames for client powersave transitions. When a
+ * station goes to sleep, we will stop transmitting to it. There is,
+ * however, a race condition: a station might go to sleep while there is
+ * data buffered on hardware queues. If the device has support for this
+ * it will reject frames, and the driver should give the frames back to
+ * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will
+ * cause mac80211 to retry the frame when the station wakes up. The
+ * driver is also notified of powersave transitions by calling its
+ * @sta_notify callback.
+ *
+ * When the station is asleep, it has three choices: it can wake up,
+ * it can PS-Poll, or it can possibly start a uAPSD service period.
+ * Waking up is implemented by simply transmitting all buffered (and
+ * filtered) frames to the station. This is the easiest case. When
+ * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
+ * will inform the driver of this with the @allow_buffered_frames
+ * callback; this callback is optional. mac80211 will then transmit
+ * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE
+ * on each frame. The last frame in the service period (or the only
+ * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
+ * indicate that it ends the service period; as this frame must have
+ * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
+ * When TX status is reported for this frame, the service period is
+ * marked has having ended and a new one can be started by the peer.
+ *
+ * Another race condition can happen on some devices like iwlwifi
+ * when there are frames queued for the station and it wakes up
+ * or polls; the frames that are already queued could end up being
+ * transmitted first instead, causing reordering and/or wrong
+ * processing of the EOSP. The cause is that allowing frames to be
+ * transmitted to a certain station is out-of-band communication to
+ * the device. To allow this problem to be solved, the driver can
+ * call ieee80211_sta_block_awake() if frames are buffered when it
+ * is notified that the station went to sleep. When all these frames
+ * have been filtered (see above), it must call the function again
+ * to indicate that the station is no longer blocked.
+ *
+ * If the driver buffers frames in the driver for aggregation in any
+ * way, it must use the ieee80211_sta_set_buffered() call when it is
+ * notified of the station going to sleep to inform mac80211 of any
+ * TIDs that have frames buffered. Note that when a station wakes up
+ * this information is reset (hence the requirement to call it when
+ * informed of the station going to sleep). Then, when a service
+ * period starts for any reason, @release_buffered_frames is called
+ * with the number of frames to be released and which TIDs they are
+ * to come from. In this case, the driver is responsible for setting
+ * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
+ * to help the @more_data paramter is passed to tell the driver if
+ * there is more data on other TIDs -- the TIDs to release frames
+ * from are ignored since mac80211 doesn't know how many frames the
+ * buffers for those TIDs contain.
+ *
+ * If the driver also implement GO mode, where absence periods may
+ * shorten service periods (or abort PS-Poll responses), it must
+ * filter those response frames except in the case of frames that
+ * are buffered in the driver -- those must remain buffered to avoid
+ * reordering. Because it is possible that no frames are released
+ * in this case, the driver must call ieee80211_sta_eosp_irqsafe()
+ * to indicate to mac80211 that the service period ended anyway.
+ *
+ * Finally, if frames from multiple TIDs are released from mac80211
+ * but the driver might reorder them, it must clear & set the flags
+ * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
+ * and also take care of the EOSP and MORE_DATA bits in the frame.
+ * The driver may also use ieee80211_sta_eosp_irqsafe() in this case.

+ * parameters. In the case where the driver buffers some frames for
+ * sleeping stations mac80211 will use this callback to tell the driver
+ * to release some frames, either for PS-poll or uAPSD.
+ * Note that if the @more_data paramter is %false the driver must check
+ * if there are more frames on the given TIDs, and if there are more than
+ * the frames being released then it must still set the more-data bit in
+ * the frame. If the @more_data parameter is %true, then of course the
+ * more-data bit must always be set.
+ * The @tids parameter tells the driver which TIDs to release frames
+ * from, for PS-poll it will always have only a single bit set.
+ * In the case this is used for a PS-poll initiated release, the
+ * @num_frames parameter will always be 1 so code can be shared. In
+ * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag
+ * on the TX status (and must report TX status) so that the PS-poll
+ * period is properly ended. This is used to avoid sending multiple
+ * responses for a retried PS-poll frame.
+ * In the case this is used for uAPSD, the @num_frames parameter may be
+ * bigger than one, but the driver may send fewer frames (it must send
+ * at least one, however). In this case it is also responsible for
+ * setting the EOSP flag in the QoS header of the frames. Also, when the
+ * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP
+ * on the last frame in the SP. Alternatively, it may call the function
+ * ieee80211_sta_eosp_irqsafe() to inform mac80211 of the end of the SP.
+ * This callback must be atomic.
+ * @allow_buffered_frames: Prepare device to allow the given number of frames
+ * to go out to the given station. The frames will be sent by mac80211
+ * via the usual TX path after this call. The TX information for frames
+ * released will also have the %IEEE80211_TX_CTL_POLL_RESPONSE flag set
+ * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case
+ * frames from multiple TIDs are released and the driver might reorder
+ * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag
+ * on the last frame and clear it on all others and also handle the EOSP
+ * bit in the QoS header correctly. Alternatively, it can also call the
+ * ieee80211_sta_eosp_irqsafe() function.
+ * The @tids parameter is a bitmap and tells the driver which TIDs the
+ * frames will be on; it will at most have two bits set.
+ * This callback must be atomic.
