382afc3d05 wil6210: move Rx reorder buffer allocation out of spinlock

3baedd9167 wil6210: tuning rings size
Tuning rings size for performance optimization.
Increasing Tx ring size, allows buffering more packets for HW, thus
eliminating idle periods which were observed with smaller ring at
high throughput, because HW was fetching packets faster than driver was
filling them into the TX ring. Rx ring was similarly increased to
avoid same problems in Rx.

69a88cc7b1 wcn36xx: initialize device defaults on start
Set up default configuration for the device when we call start.
The defaults come from dumps from the prima driver for the same
hardware.

This fixes transmit A-MPDU; previously only one MPDU would be
sent per A-MPDU due to missing MAX_MPDUS_IN_AMPDU setting.

0b83795a11 iwlwifi: mvm: fix rx chains configuration in phy ctxt cmd
In the PHY_CTXT command sent to the FW the TX chains were
indeed configured by the values of both FW TLVs and of NVM,
but the RX chains were left out and configured only by FW
TLV.

This causes problems in 4165 HW, where there are 1x1
antennas, and the wrong configuration denies the driver
from connecting to the AP.

afb8891740 iwlwifi: pcie: support secured boot flow for family 8000 B step
The driver loads the 2 CPU sections, then it needs to let
the firmware know to start the authentication of the
sections. This is done by writing the relevants bits to
FH_UCODE_LOAD_STATUS.

For CPU1, the driver sets the lower 16 bits. For both CPUs,
the driver sets all the 32 bits.

c5d679a55d iwlwifi: mvm: use a new API for enabling STBC
The new API tells the FW that it's allowed to use STBC
but the FW will decide on its own whether to use STBC
or SISO (and in the future Beamformer).
Keep support for the old API which sets STBC explicitly
in the rates in the LQ table while we still support old
FW revisions.
