Thermal cooling device support is added to control the temperature by
throttling the data transmission for the given duration. Throttling is
done by adjusting Tx period by given percentage of time. The thermal
device allows user to configure duty cycle.

Throttling can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder

To set duty cycle as 80%,

Add runtime configuration for bitrate mask. This update firmware rate
control to add a boundary on top of table to limit the rate selection
for each peer, so when user set bitrates vht-mcs-5 1:9, which actually
means nss = 1 mcs = 0~9. This only applies to data frames as for other
mgmt, mcast, bcast still use legacy rates as it is.

Note that driver does not support GI configuration.

Example:
iw dev wlan0 set bitrates vht-mcs-5 1:9 he-mcs-5 2:7
iw dev wlan0 set bitrates legacy-5 6 he-mcs-5 2:0-11
