[PATCH net V2 0/2] libphy: Add phy specific function to access mmd

[Vince Bridgers <vbridgers2013@gmail.com>]

This set of patches addresses a problem found with the Micrel ksz9021 phy and
libphy, where the ksz9021 phy does not support mmd extended register access
per the IEEE specification as assumed by libphy. The first patch adds a
framework for phy specific support to specify their own function to access
extended phy registers, return a failure code if not supported, or to default
to libphy's IEEE defined method for accessing the mmd extended phy registers.

This issue was found by using the Synopsys EMAC and a Micrel ksz9021 phy on the
Altera Cyclone 5 SOC development kit. This patch was tested on the same system
in both positive and negative test cases.

Please consider including this patch if you find these modifications
acceptable.

V2: Split the original patch submission into seperate patches for the libphy
    framework required for the modification and for the Micrel Phy.
