Index N (1-63) can be set using a fixed power to iw of -N*100.
e.g. index 45: iw dev <interface> set txpower fixed -4500
The current override index, if any, is displayed as a negative number by iw dev <interface> info. To disable the override, use a non-negative power value.
The TX power index override can still be set on load by using the module parameter rtw_tx_pwr_idx_override, but changing it through sysfs is (still) ineffective.
Tested on AWUS036ACH with a spectrum analyzer connected to the output.
