Hi all,
there is a series of patches I authored to cleanup MT7620 ethernet driver and fix MT7620 ethernet for external Atheros switches like AR8327 or QCA8337
Originally, I posted just a fix, but I continued finding other small issues and the cleanup grew to the point where it affects all MT7620 devices in some way or another
The changes should be backported to the new stable branch 21.02, but before that it would be nice to get as many testers as possible
The patches are in master as of 24 hours ago, so the latest SNAPSHOT image can be used to test
https://downloads.openwrt.org/snapshots/targets/ramips/mt7620/
Keep in mind that there is a small chance that when flashing SNAPSHOT images that things can go wrong and always backup flash and have a recovery method ready
if everything is good, please comment at this PR including what your MT7620 device is
