In case of traffic on multiple TIDs where one is aggregated and the other is not RS would toggle between considering traffic vs. the station as aggregated and not aggregated. Instead consider the sta state as aggregated as long as there's at least one TID aggregated. This limitation is because the rates table is kept per station and not per TID.

Currently BA notifications which don't reclaim any frames would not cause the RS to be called as no skbs are passed to mac80211. This is not optimal as RS can benefit from the statistics of sent vs. acked of such a BA. This can improve the reaction time of the RS algorithm. Also, an upcoming change in the firmware would cause BA timeout to be reported as a BA notif with 0 acked so this change is required for that as well.

This is a tradeoff between enabling better throughput for bursty traffic and low latency. The number 6 was found to be a good tradeoff for the Miracast use case which is the major use case for low latency.

Enable RS to get updated directly via iwl_mvm_rs_tx_status which will be called by the driver and not via mac80211 rate control. This is required for a following patch to report on BAs which do not cause the BA window to progress. Also this is a first step in decoupling rs from the mac80211 rate control.

Improve the initial tx rate and antenna selection to be based on the rssi of the last rx. This avoids starting at the lowest legacy rate always and requiring more tx traffic to "climb" up the rates. Since this option might cause trouble in certain setups, allow to disable it by default.

The scheduler is a HW sub-block that directs the work of the Flow Handler by issuing requests for frame transfers, specifying source and destination. Its primary function is to allocate flows into the TX FIFOs based upon a pre-determined mapping. The driver has some responsibilities to the scheduler, namely initialising and maintaining the hardware registers. This is currently done by directly accessing them, which can cause races with the firmware also accessing the registers. To address this problem, change the driver to no longer directly access the registers but go through the firmware for this if the firmware has support for DQA and thus the new command.

Introduce new tx command flag (TX_CMD_FLG_WRITE_TX_POWER) which requests the fw to update the tx power value at some constant offset. Set this flag when transmitting either TPC report or Link measurement report action frames.

There was some confusion concerning the units of the beacon interval. The driver assumed that it was in msec where it was in TU - so fix that. Skip over dtim was capped by 300TU where it should be by 306TU. It should also be subjected to several conditions: Not a DFS channel, dtim period < 10, and the multicast wake-lock is off. Concerning multicast lock - there is an implementation gap in the supplicant, so just leave a TODO.

When not updating the quota, the new command shouldn't be stored as otherwise slowly drifting quota would never update the firmware. Fix this by storing the command only when it was also sent. Since the error message also only makes sense when attempting to send the command, just short-circuit the function when there's no need to send the command.

Reading the temperature directly from the hardware, without the help of the firmware, is a complex process and is not entirely the same for different hardware. Also, some NICs don't easily allow access to the sensors when the firmware is not running, which would add even more complexity to the code. To reduce the code complexity and to avoid code duplication between the firmware and the driver, boot the firmware briefly to read the current temperature while in CT kill mode.

When updating quota in the firmware, it has to reset quite a bit of internal state, which apparently can have an adverse impact on its operation. Avoid that by only updating the quota command when there are any signification changes, i.e. added/removed bindings or changes in quota that are bigger than 8 TU within a binding.
