This was tested on a ARM926 base SoC with an IP based ethernet MAC (10/100 MBit) together with a Realtek RTL8201 MII and a SMCSC

An Ethernet MAC needs to know the medium speed (10/100/1000 Mbps) of an RMII PHY in order to correctly interpret data originating
from that PHY. The function mii_check_media() has been extended to allow retrieval of the medium speed by a MAC driver. A trivial
modification to existing MAC drivers will allow them to cover operation with both MII and RMII PHYs.

Queued for review.
