Hi Antoine Florian did some work for c22 PHYs so that the existing link state could be used at boot. So for example, the bootloader configured the PHY up and it got link, there is no need to down/up the PHY when linux takes control. The networking comes up faster that way. Can this work for this PHY? Andrew
