Is there a specific reason why c22 is probed first? Reversing the order would solve the issue we speak about here. c45-probing of c22-only PHY's shouldn't return false positives (at least at a first glance).

That would likely cause problems for the I2f MDIO driver, since a C45 read is indistinguishable from a C22 write on the I2C bus.
