> As reported by Maggie Mae Roxas, the mvneta driver doesn't behave
> properly in 10 Mbit/s mode. This is due to a misconfiguration of the
> MVNETA_GMAC_AUTONEG_CONFIG register: bit MVNETA_GMAC_CONFIG_MII_SPEED
> must be set for a 100 Mbit/s speed, but cleared for a 10 Mbit/s speed,
> which the driver was not properly doing. This commit adjusts that by
> setting the MVNETA_GMAC_CONFIG_MII_SPEED bit only in 100 Mbit/s mode,
> and relying on the fact that all the speed related bits of this
> register are cleared at the beginning of the mvneta_adjust_link()
> function.
