This is also going to be needed for stmmac, which can operate in SGMII mode acting as if it were a PHY to allow a SGMII MAC-to-MAC connection to be established. As noted by the kernel build bot, there are several other locations that need to be updated whenever a new phy interface is added. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
