Research direction

Reproduce the reported mt7915 behavior using the supplied /etc/config/wireless settings on OpenWrt v24.10.0-rc2, then compare the configured txpower with the iwinfo output. Trace the mt7915 driver’s transmit-power and regulatory handling; done means option txpower is honored and iwinfo reports the expected value.
