22 * DOC: DQA - Dynamic Queue Allocation -introduction
24 * Dynamic Queue Allocation (AKA "DQA") is a feature implemented in iwlwifi
25 * driver to allow dynamic allocation of queues on-demand, rather than allocate
26 * them statically ahead of time. Ideally, we would like to allocate one queue
27 * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2
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

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
43 * queue.

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.
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.
58 * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a
