Browse source 
TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.

When we setup channel to connect an AP, it does full calibration. When
switching bands or channels, it needs to reset hardware status to prevent
use wrong feedback of previous transmission.

To do TX power compensation reflecting current temperature, it loads tables
of compensation values into registers according to channel and band group.
