This driver can be used for a MAC - MAC fixed link connection. In order to do so, please update the devicetree fixed link node as per https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/net/fixed-link.txt and set the phy-mode to "moca" ( https://github.com/Xilinx/linux-xlnx/blob/master/include/linux/phy.h )
