Life got in the way of following up sooner -- apologies for the delay. Since submitting, Nick (morrownr, USB-WiFi maintainer) has tested and confirmed the fix works on his MT7921U adapter -- 33 dBm on 2.4 GHz and 24 dBm on 5 GHz, both matching regulatory limits as expected. I noticed Bryam Vargas recently submitted a competing fix that updates txpower_cur in mt76_connac_mcu_set_rate_txpower(). That function is only called from mt7921_set_sar_specs(), so it wouldn't fire during normal AP association or channel changes. My v2 hooks bss_info_changed() on BSS_CHANGED_TXPOWER, which covers the common case. Happy to rework if you'd prefer a different approach -- just wanted to make sure this wasn't lost in the shuffle. Thanks, Lucid Duck
