> ChangeLog v1->v2:
> - Drop <linux/delay.h> from an earlier iteration.
> - Implement an .config_aneg() routine that does nothing: the
>   imroved genphy_config_aneg() makes the device fail as of
>   v4.18-rc1 and the device seems to feel best like this: it
>   comes up in autonegotiation mode and we do not try to instruct

> - Use some MII defines when reading/writing registers.
> - Collect Florian's ACK.

Applied.
