Subject: [PATCH net-next v2 0/4] net: add EEE support for KSZ9477 switch series

changes v2:
- use phydev->supported instead of reading MII_BMSR regiaster
- fix @get_eee > @set_eee

With this patch series we provide EEE support for KSZ9477 family of switches.
According to my tests, on a system with KSZ8563 switch and 100Mbit idle link,
we consume 0,192W less power per port if EEE is enabled.

Oleksij Rempel (4):
  net: phy: add driver specific get/set_eee support
  net: phy: micrel: add EEE configuration support for KSZ9477 variants
    of PHYs
  net: phy: micrel: disable 1000Mbit EEE support if 1000Mbit is not
    supported
  net: dsa: microchip: enable EEE support
