+/**
+ * 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 coresponsding %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. In
+ * that case, we need to drain all the frames for that client from the AC queues
+ * that are shared with the other clients. Only then, we can remove the STA in
+ * the fw. In order to do so, we track the non-AMPDU packets for each station.
+ * If mac80211 removes a STA and if it still has non-AMPDU packets pending in
+ * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all
+ * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped
+ * (we know about it with its Tx response), we remove the station in fw and set
+ * it as %NULL in %fw_id_to_mac_id: this is the purpose of
+ * %iwl_mvm_sta_drained_wk.
+ */
+
+/**
+ * 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 the
+ * non-aggregation frames 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 how many frames we have in these queues so that it can
+ * properly handle trigger frames.
+ * When the a trigger frame is received, mac80211 tells the driver to send
+ * frames from the AMPDU queues or AC queue depending on which queue are
+ * delivery-enabled and what TID has frames to transmit (Note that mac80211 has
+ * all the knowledege 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 alseep any more.
+ * This is done by %iwl_mvm_sta_modify_ps_wake.

+/**
+ * DOC: Time Events - what is it?
+ *
+ * Time Events are a fw feature that allows the driver to control the presence
+ * of the device on the channel. Since the fw supports multiple channels
+ * concurrently, the fw may choose to jump to another channel at any time.
+ * In order to make sure that the fw is on a specific channel at a certain time
+ * and for a certain duration, the driver needs to issue a time event.
+ *
+ * The simplest example is for BSS association. The driver issues a time event,
+ * waits for it to start, and only then tells mac80211 that we can start the
+ * association. This way, we make sure that the association will be done
+ * smoothly and won't be interrupted by channel switch decided within the fw.
+ */
+
+ /**
+ * DOC: The flow against the fw
+ *
+ * When the driver needs to make sure we are in a certain channel, at a certain
+ * time and for a certain duration, it sends a Time Event. The flow against the
+ * fw goes like this:
+ * 1) Driver sends a TIME_EVENT_CMD to the fw
+ * 2) Driver gets the response for that command. This response contains the
+ * Unique ID (UID) of the event.
+ * 3) The fw sends notification when the event starts.
+ *
+ * Of course the API provides various options that allow to cover parameters
+ * of the flow.
+ * What is the duration of the event?
+ * What is the start time of the event?
+ * Is there an end-time for the event?
+ * How much can the event be delayed?
