====================
marvell10g tunable and power saving support

This patch series adds support for:
- mdix configuration (auto, mdi, mdix)
- energy detect power down (edpd)
- placing in edpd mode at probe

for both the 88x3310 and 88x2110 PHYs.

Antione, could you test this for the 88x2110 PHY please?

v3: fix return code in get_tunable/set_tunable
v2: fix comments from Antione.
