Subject: [PATCH net-next v8 4/8] net: phy: Keep track of EEE configuration

From: Andrew Lunn <andrew@lunn.ch>

Have phylib keep track of the EEE configuration. This simplifies the
MAC drivers, in that they don't need to store it.

Future patches to phylib will also make use of this information to
further simplify the MAC drivers.
