Therefore, create a new Xilinx job to test GEM (Gigabit Ethernet MAC) controller passthrough to a dom0less domU. By passing "gem-passthrough" as a test variant, the test will instruct the ImageBuilder to use "eth0.dtb" (passthrough dtb stored under tftp server root) as a guest dtb and to add "xen,passthrough" dtb property to "/amba/ethernet@ff0e0000" node. The guest itself will try to bringup the network interface, obtain dynamically IP address and ping the default gateway.
