-Subject: [PATCH] enetc: Use DT protocol information to set up the ports
-
-Use DT information rather than in-band information from bootloader to
-set up MAC for XGMII. For RGMII use the DT indication in addition to
-RGMII defaults in hardware.
-However, this implies that PHY connection information needs to be
-extracted before netdevice creation, when the ENETC Port MAC is
-being configured.
