It seems that ukphy(4) was picked up to serve your PHY hardware.
I guess ukphy(4) is not right phy driver for the hardware as it could
result in non-working driver. Would you show me the ukphy(4) output of
verbosed boot message?(In verbosed boot mode, ukphy(4) may have printed
OUI/model number of the PHY hardware.)
