Thanks for the quick summary. Note that regarding Florian's report, on the WAX206 the RTL8221B-BV-VG PHY is connected to port 5 of the MT7531AE switch [1] and hence NOT to the MAC of MT7622 SoC. So it can of course still be an issue with that PHY (which has been giving us some trouble in general), but I'd be very confused if you insist that it would be caused by mtk_eth_soc, and would ask you to explain why you think that would be the case.
