Description

The device uses PA, mt7603e starts normally, the phone can't find wifi, the test shows that the sending power is very low. But the MTK official driver PA can work normally.
Modify e2p After the PA is turned off, the wifi signal is very poor.

How can I modify the PA to work properly?
Thanks!

Research direction

No source file, test, or entry point is named. Start by tracing MT7603 PA and E2P transmit-power handling in the driver and compare the reported 12 dBm behavior with the official MTK driver. Done would require a reproducible configuration or code change that restores normal transmit power while preserving reception.
