/**
+ * 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.
