parentnet: phy: add __set_linkmode_max_speed (diff)
net: phy: add phy_speed_down_core and phy_resolve_min_speed
phy_speed_down_core provides most of the functionality for phy_speed_down. It makes use of new helper phy_resolve_min_speed that is based on the sorting of the settings[] array. In certain cases it may be helpful to be able to exclude legacy half duplex modes, therefore prepare phy_resolve_min_speed() for it. v2: - rename __phy_speed_down to phy_speed_down_core Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
