[PATCH] rtw88: 8821c: apply CCK PD level which calculates from dynamic mechanism

[Ping-Ke Shih]

From: vincent_fann <vincent_fann@realtek.com>

Hal function must follow the value that calculates from dynamic mechanism.
Force to set new_lvl to 4 damages receiving ability. System will not able
to reconnect to the AP if wifi unexpected disconnecting at this moment.

The real name looks to be just a copy of username, badly configured git
maybe? I can fix it during commit, how does Vincent format his name in
regular email? Does this look ok:

Vincent Fann <vincent_fann@realtek.com>
