Firmware Resets

I have upgraded my DIR-860L device from 19.07.1 to 19.07.4 (which means the mt76 driver received this update: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=9da31d0fb402f5ee3f3973ee07625942634a38fb) and now my kernel logs are getting spammed by this, over and over and over again:

I experience small hiccups in the my connection, supposedly due to the firmware resetting. I did see these message very rarely on 19.07.1 as well, but not as often as I do on 19.07.4. If you need any additional information for debugging this, please let me know!

Start with the linked mt76 update commit and the mt76x2e restart messages in the report; compare the 19.07.1 and 19.07.4 driver behavior and trace the hardware-restart path. Done means identifying and fixing the regression so the DIR-860L no longer repeatedly resets firmware or spams these logs, with validation on that device.
