If unsure, don't enable this option, as some programs might
expect incoming broadcasts for their normal operations.
config IWLWIFI_UAPSD
bool "enable U-APSD by default"
depends on IWLMVM
help
Say Y here to enable U-APSD by default. This may cause
interoperability problems with some APs, manifesting in lower than
expected throughput due to those APs not enabling aggregation
If unsure, say N.

/**
* 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.
