dwmac-socfpga uses MII, RMII, GMII, RGMII, SGMII and 1000BASE-X interface modes, and supports the Lynx PCS. The Lynx PCS will only be used for SGMII and 1000BASE-X modes, with the MAC programmed to use GMII or MII mode to talk to the PCS. This suggests that the Synopsys optional dwmac PCS is not present. None of the DTS files set "mac-mode", so mac_interface will be identical to phy_interface. Convert dwmac-socfpga to use phy_interface when determining the interface mode rather than mac_interface.
