This looks suspicious, phy_probe() takes the driver supported features
and assigns it to phydev->supported, and phydev->advertising, is not
that working somehow?
genphy_config_init() does look at the current MII_BMRS value to
determine what is supported by the PHY, and masks it in
phydev->supported, so that could indeed be an issue if we had not had a
change to mask with the supported modes before.
I think we need more explanation here as to what kind of bug you may
have been observing, there could be one.
