+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.
