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

Also this is a first step in decoupling rs from the

Improve the initial tx rate and antenna selection to be based on

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.

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.

max_rate_idx constraint is deprecated and it's handling is

was considered in HT/VHT. In most cases there was no side effect
as max_rate_idx was set to -1 but in certain cases like P2P
it got set to an actual rate idx which would limit the maximum
