[mdio] Add MDIO support for "extended" registers as defined by IEEE 802.3 Clause 45.

2015-12-26T17:22:02+00:00

IEEE 802.3 Clause 45 added backwards-compatible support for 2^16 PHY registers
through the addition of an additional device address frame.

Clause 45 addressing is used in 10Gbe PHYs, 802.3az EEE registers, etc. It may
make sense to provide a similar extension to the miibus interface, but I've
refrained from unilaterally doing so here.

[mdio] migrate mdiobus out of etherswitch and into a top-level device of its own.

2015-12-26T02:31:39+00:00

The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.
