I was wondering about the overlap and the best way to address it.

My patchset is also a bit big, and getting bigger. So it might make
sense to split out some of the bits you need and get them merged
first.

You need the MAC indicating it is EEE capable. I don't store that
information explicitly, but that is a quick simple change. You also
need phydev->tx_lpi_enabled. Anything else?
