Description
Hi, I'm trying to use dynamic tx power adjustment with my E8450 router.
I saw the comment "firmware dynamically adjusts PD threshold so skip manual control",
so I expected the router to dynamically adjust tx power if I call mt7915_mcu_enable_obss_spr with SPR_ENABLE_DPD and SPR_ENABLE_SD in mcu.c to enable DPD.
I tested with my two E8450 routers, but tx power remained nearly constant in the presence of about -70 dBm co-channel interference.
Is there a way to make the E8450 dynamically adjust tx power?
If not, does BPI-R4 eqipped with mt7988A support this feature?

Research direction
Start in mcu.c at mt7915_mcu_enable_obss_spr and trace how SPR_ENABLE_DPD and SPR_ENABLE_SD are handled. Compare the E8450 behavior described here with the mt7988A/BPI-R4 support, and consider the issue resolved when the firmware or driver capability and any required change are clearly established.
