  * DOC: DQA - Dynamic Queue Allocation -introduction
  *
  * Dynamic Queue Allocation (AKA "DQA") is a feature implemented in iwlwifi
  * driver to allow dynamic allocation of queues on-demand, rather than allocate
  * them statically ahead of time. Ideally, we would like to allocate one queue
  * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2
  * even if it also needs to send traffic to a sleeping STA1, without being
  * blocked by the sleeping station.
  *
  * Although the queues in DQA mode are dynamically allocated, there are still
  * some queues that are statically allocated:
  *  TXQ #0 - command queue
  *  TXQ #1 - aux frames
  *  TXQ #2 - P2P device frames
  *  TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames
  *  TXQ #4 - BSS DATA frames queue
  *  TXQ #5-8 - Non-QoS and MGMT frames queue pool
  *  TXQ #9 - P2P GO/SoftAP probe responses
  *  TXQ #10-31 - DATA frames queue pool
  * The queues are dynamically taken from either the MGMT frames queue pool or
  * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every
  * queue.
  *
  * When a frame for a previously unseen RA/TID comes in, it needs to be deferred
  * until a queue is allocated for it, and only then can be TXed. Therefore, it
  * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called
  * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames.
  *
  * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT
  * queues in the pool. If there is no longer a free MGMT queue to allocate, a
  * queue will be allocated from the DATA pool instead. Since QoS NDPs can create
  * a problem for aggregations, they too will use a MGMT queue.
  *
  * When adding a STA, a DATA queue is reserved for it so that it can TX from
  * it. If no such free queue exists for reserving, the STA addition will fail.
  *
  * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a
  * new RA/TID comes in for an existing STA, one of the STA's queues will become
  * shared and will serve more than the single TID (but always for the same RA!).
  *
  * When a RA/TID needs to become aggregated, no new queue is required to be
  * allocated, only mark the queue as aggregated via the ADD_STA command. Note,
  * however, that a shared queue cannot be aggregated, and only after the other
  * TIDs become inactive and are removed - only then can the queue be
  * reconfigured and become aggregated.
  *
  * When removing a station, its queues are returned to the pool for reuse. Here
  * we also need to make sure that we are synced with the worker thread that TXes
  * the deferred frames so we don't get into a situation where the queues are
  * removed and then the worker puts deferred frames onto the released queues or
  * tries to allocate new queues for a STA we don't need anymore.
  */
 
 /**
  * DOC: station table - introduction
  *
  * The station table is a list of data structure that reprensent the stations.
  * In STA/P2P client mode, the driver will hold one station for the AP/ GO.
  * In GO/AP mode, the driver will have as many stations as associated clients.
  * All these stations are reflected in the fw's station table. The driver
  * keeps the fw's station table up to date with the ADD_STA command. Stations
  * can be removed by the REMOVE_STA command.
  *
  * All the data related to a station is held in the structure %iwl_mvm_sta
  * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.
  * This data includes the index of the station in the fw, per tid information
  * (sequence numbers, Block-ack state machine, etc...). The stations are
  * created and deleted by the %sta_state callback from %ieee80211_ops.
  *
  * The driver holds a map: %fw_id_to_mac_id that allows to fetch a
  * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw
  * station index. That way, the driver is able to get the tid related data in
  * O(1) in time sensitive paths (Tx / Tx response / BA notification). These
  * paths are triggered by the fw, and the driver needs to get a pointer to the
  * %ieee80211 structure. This map helps to get that pointer quickly.
  */
 
 /**
  * DOC: station table - locking
  *
  * As stated before, the station is created / deleted by mac80211's %sta_state
  * callback from %ieee80211_ops which can sleep. The next paragraph explains
  * the locking of a single stations, the next ones relates to the station
  * table.
  *
  * The station holds the sequence number per tid. So this data needs to be
  * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack
  * information (the state machine / and the logic that checks if the queues
  * were drained), so it also needs to be accessible from the Tx response flow.
  * In short, the station needs to be access from sleepable context as well as
  * from tasklets, so the station itself needs a spinlock.
  *
  * The writers of %fw_id_to_mac_id map are serialized by the global mutex of
  * the mvm op_mode. This is possible since %sta_state can sleep.
  * The pointers in this map are RCU protected, hence we won't replace the
  * station while we have Tx / Tx response / BA notification running.
  *
  * If a station is deleted while it still has packets in its A-MPDU queues,
  * then the reclaim flow will notice that there is no station in the map for
  * sta_id and it will dump the responses.
  */
 
 /**
  * DOC: station table - internal stations
  *
  * The FW needs a few internal stations that are not reflected in
  * mac80211, such as broadcast station in AP / GO mode, or AUX sta for
  * scanning and P2P device (during the GO negotiation).
  * For these kind of stations we have %iwl_mvm_int_sta struct which holds the
  * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.
  * Usually the data for these stations is static, so no locking is required,
  * and no TID data as this is also not needed.
  * One thing to note, is that these stations have an ID in the fw, but not
  * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id
  * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of
  * pointers from this mapping need to check that the value is not error
  * or NULL.
  *
  * Currently there is only one auxiliary station for scanning, initialized
  * on init.
  */
 
 /**
  * DOC: station table - AP Station in STA mode
  *
  * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:
  * %ap_sta_id. To get the point to the corresponding %ieee80211_sta,
  * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove
  * the AP station from the fw before setting the MAC context as unassociated.
  * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is
  * removed by mac80211, but the station won't be removed in the fw until the
  * VIF is set as unassociated. Then, %ap_sta_id will be invalidated.
  */
 
 /**
  * DOC: station table - Drain vs. Flush
  *
  * Flush means that all the frames in the SCD queue are dumped regardless the
  * station to which they were sent. We do that when we disassociate and before
  * we remove the STA of the AP. The flush can be done synchronously against the
  * fw.
  * Drain means that the fw will drop all the frames sent to a specific station.
  * This is useful when a client (if we are IBSS / GO or AP) disassociates.
  */
 
 /**
  * DOC: station table - fw restart
  *
  * When the fw asserts, or we have any other issue that requires to reset the
  * driver, we require mac80211 to reconfigure the driver. Since the private
  * data of the stations is embed in mac80211's %ieee80211_sta, that data will
  * not be zeroed and needs to be reinitialized manually.
  * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us
  * that we must not allocate a new sta_id but reuse the previous one. This
  * means that the stations being re-added after the reset will have the same
  * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id
  * map, since the stations aren't in the fw any more. Internal stations that
  * are not added by mac80211 will be re-added in the init flow that is called
  * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to
  * %iwl_mvm_up.
  */
 
 /**
  * DOC: AP mode - PS
  *
  * When a station is asleep, the fw will set it as "asleep". All frames on
  * shared queues (i.e. non-aggregation queues) to that station will be dropped
  * by the fw (%TX_STATUS_FAIL_DEST_PS failure code).
  *
  * AMPDUs are in a separate queue that is stopped by the fw. We just need to
  * let mac80211 know when there are frames in these queues so that it can
  * properly handle trigger frames.
  *
  * When a trigger frame is received, mac80211 tells the driver to send frames
  * from the AMPDU queues or sends frames to non-aggregation queues itself,
  * depending on which ACs are delivery-enabled and what TID has frames to
  * transmit. Note that mac80211 has all the knowledge since all the non-agg
  * frames are buffered / filtered, and the driver tells mac80211 about agg
  * frames). The driver needs to tell the fw to let frames out even if the
  * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count.
  *
  * When we receive a frame from that station with PM bit unset, the driver
  * needs to let the fw know that this station isn't asleep any more. This is
  * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the
  * station's wakeup.
  *
  * For a GO, the Service Period might be cut short due to an absence period
  * of the GO. In this (and all other cases) the firmware notifies us with the
  * EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we
  * already sent to the device will be rejected again.
  *
  * See also "AP support for powersaving clients" in mac80211.h.
