Subject: e1000e: add support for 82577/82578 GbE LOM parts
This patch provides support for the next generation Intel desktop
and mobile gigabit ethernet LOM adapters. These adapters are the
follow-on parts to the LOMs tied to the prior ICH chipsets and are
comprised of a MAC in the PCH chipset and an external PHY (82577 for
mobile and 82578 for desktop versions). New features consist of PHY
wakeup to save power by completely turning off the MAC while in Sx
state, and 4K jumbo frames.

Subject: e1000e: Expose MDI-X status via ethtool change
Ethtool is a standard way of getting information about
ethernet interfaces. We enhance ethtool kernel interface
& e1000e to make the MDI-X status readable via ethtool in
userspace.
