The driver has the same code as the one of the STM32H7. When the PHY did not clear the reset bit in time, stm32_phyinit() returned the result of the last MDIO read. The bus reads all ones when the PHY does not answer yet, and that read succeeds, so the function returned OK and the driver went on with its default of 10 Mbps and half duplex, while the PHY could negotiate 100 Mbps and full duplex. Return -ETIMEDOUT, so that bringing the interface up fails and the failure is not hidden. It builds for nucleo-h563zi:netnsh, but it was not tested on hardware. Signed-off-by: Daniel P.
