Subject: [PATCH net-next 0/3] net: phy: add and use phy_check_downshift

So far PHY drivers have to check whether a downshift occurred to be
able to notify the user. To make life of drivers authors a little bit
easier move the downshift notification to phylib. phy_check_downshift()
compares the highest mutually advertised speed with the actual value
of phydev->speed (typically read by the PHY driver from a
vendor-specific register) to detect a downshift.

Heiner Kallweit (3):
  net: phy: add and use phy_check_downshift
  net: phy: marvell: remove downshift warning now that phylib takes care
  net: phy: aquantia: remove downshift warning now that phylib takes
    care
