The switch detection on the NEXX WT3020 was broken by commit
aa5014d
and/or
39b5218

No ethernet interface is present, and running swconfig list returns nothing.
Everything was fine after reverting these commits.

Thanks a lot for the bootlog.

Would you please apply https://www.kresin.me/files/mt7620n_mdio.patch to an unmodified tree and check if it fixes the issue.

It might be that I introduced more issues with the mentioned commits and I would like to fix all of them.
