This patch enables IEEE802.3az (a.k.a. Energy Efficient Ethernet) on the
new 82579 LOMs.  An optional module parameter is provided to disable the
feature if desired.

IEEE802.3az has not been finalised and I heard that some significant
changes are still required relative to the latest draft.  Given that,
any current implementation may not be interoperable with PHYs that
implement the final standard and it doesn't seem like a great idea to
enable it by default.
