libphy was originally written assuming all phy devices support clause 45 access extensions to the mmd registers through the indirection registers located within the first 16 phy registers. This assumption is not true in all cases, and one specific example is the Micrel ksz9021 10/100/1000 Mbps phy. Using the stmmac driver, accessing the mmd registers to query and configure energy efficient Ethernet (EEE) features yielded unexpected behavior. This patch adds mmd access functions to the phy driver that can be overriden by the phy specific driver if the phy does not support this mechanism or uses it's own non-standard access mechanism. By default, the IEEE Compatible clause 45 access mechanism described in clause 22 is used. With this patch, EEE query/configure functions as expected using the stmmac and the Micrel ksz9021 phy.
