Ideally, we would like to allocate one queue 27 * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2 28 * even if it also needs to send traffic to a sleeping STA1, without being 29 * blocked by the sleeping station. 30 * 31 * Although the queues in DQA mode are dynamically allocated, there are still 32 * some queues that are statically allocated: 33 * TXQ #0 - command queue 34 * TXQ #1 - aux frames 35 * TXQ #2 - P2P device frames 36 * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames 37 * TXQ #4 - BSS DATA frames queue 38 * TXQ #5-8 - Non-QoS and MGMT frames queue pool 39 * TXQ #9 - P2P GO/SoftAP probe responses 40 * TXQ #10-31 - DATA frames queue pool 41 * The queues are dynamically taken from either the MGMT frames queue pool or 42 * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every 43 * queue. 44 * 45 * When a frame for a previously unseen RA/TID comes in, it needs to be deferred 46 * until a queue is allocated for it, and only then can be TXed. Therefore, it 47 * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called 48 * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames. 49 * 50 * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT 51 * queues in the pool. If there is no longer a free MGMT queue to allocate, a 52 * queue will be allocated from the DATA pool instead. Since QoS NDPs can create 53 * a problem for aggregations, they too will use a MGMT queue. 54 * 55 * When adding a STA, a DATA queue is reserved for it so that it can TX from 56 * it. If no such free queue exists for reserving, the STA addition will fail. 57 * 58 * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a 59 * new RA/TID comes in for an existing STA, one of the STA's queues will become 60 * shared and will serve more than the single TID (but always for the same RA!). 61 * 62 * When a RA/TID needs to become aggregated, no new queue is required to be 63 * allocated, only mark the queue as aggregated via the ADD_STA command. Note, 64 * however, that a shared queue cannot be aggregated, and only after the other 65 * TIDs become inactive and are removed - only then can the queue be 66 * reconfigured and become aggregated. 67 * 68 * When removing a station, its queues are returned to the pool for reuse. Here 69 * we also need to make sure that we are synced with the worker thread that TXes 70 * the deferred frames so we don't get into a situation where the queues are 71 * removed and then the worker puts deferred frames onto the released queues or 72 * tries to allocate new queues for a STA we don't need anymore. 73 */ 74 75 /** 76 * DOC: station table - introduction 77 * 78 * The station table is a list of data structure that reprensent the stations. 79 * In STA/P2P client mode, the driver will hold one station for the AP/ GO. 80 * In GO/AP mode, the driver will have as many stations as associated clients. 81 * All these stations are reflected in the fw's station table. The driver 82 * keeps the fw's station table up to date with the ADD_STA command. Stations 83 * can be removed by the REMOVE_STA command. 84 * 85 * All the data related to a station is held in the structure %iwl_mvm_sta 86 * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area. 87 * This data includes the index of the station in the fw, per tid information 88 * (sequence numbers, Block-ack state machine, etc...). The stations are 89 * created and deleted by the %sta_state callback from %ieee80211_ops. 90 * 91 * The driver holds a map: %fw_id_to_mac_id that allows to fetch a 92 * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw 93 * station index. That way, the driver is able to get the tid related data in 94 * O(1) in time sensitive paths (Tx / Tx response / BA notification). These 95 * paths are triggered by the fw, and the driver needs to get a pointer to the 96 * %ieee80211 structure. This map helps to get that pointer quickly. 97 */ 98 99 /** 100 * DOC: station table - locking 101 * 102 * As stated before, the station is created / deleted by mac80211's %sta_state 103 * callback from %ieee80211_ops which can sleep. The next paragraph explains 104 * the locking of a single stations, the next ones relates to the station 105 * table. 106 * 107 * The station holds the sequence number per tid. So this data needs to be 108 * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack 109 * information (the state machine / and the logic that checks if the queues 110 * were drained), so it also needs to be accessible from the Tx response flow. 111 * In short, the station needs to be access from sleepable context as well as 112 * from tasklets, so the station itself needs a spinlock. 113 * 114 * The writers of %fw_id_to_mac_id map are serialized by the global mutex of 115 * the mvm op_mode.

In order to "reserve" them a sta_id in %fw_id_to_mac_id 136 * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of 137 * pointers from this mapping need to check that the value is not error 138 * or NULL. 139 * 140 * Currently there is only one auxiliary station for scanning, initialized 141 * on init. 142 */ 143 144 /** 145 * DOC: station table - AP Station in STA mode 146 * 147 * %iwl_mvm_vif includes the index of the AP station in the fw's STA table: 148 * %ap_sta_id.

Note that mac80211 has all the knowledge since all the non-agg 199 * frames are buffered / filtered, and the driver tells mac80211 about agg 200 * frames).
