As far as I see, you are not using clean mainline stable kernel. All changes which make your kernel to need an external PHY driver are _not_ in v5.10.198. You will need to cherrypick at least 28 last patches from this stack: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/net/usb/asix_devices.c?h=v6.6-rc6 and some from here too: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/net/usb/usbnet.c?h=v6.6-rc6 Regards, Oleksij -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
