The PHYs can operate with Clause-22 and Clause-45 MDIO. When using Clause-45 it is desireable to avoid rate-adapter mode and rather have the MAC interface mode follow the PHY speed. The PHYs support 2500Base-X for 2500M, and Cisco SGMII for 1000M/100M/10M. Also prepare support for proprietary RealTek HiSGMII mode which will be needed for situations when used with RealTek switch or router SoCs such as RTL93xx. Add support for Link Down Power Saving Mode (ALDPS) which is already supported for older RTL821x series 1GbE PHYs. Make sure that link-partner advertised modes are only used if the advertisement can be considered valid. Otherwise we are seeing false-positives warning about downscaling eventhough higher speeds are not actually advertised by the link partner. While at it, improve the driver by using existing macros and inline functions which are not actually vendor specific.
