The ++first level describes the ethernet controller itself and the second level ++describes up to 3 ethernet port nodes within that controller. The reason for ++the multiple levels is that the port registers are interleaved within a single ++set of controller registers. Each port node describes port-specific properties. ++ ++Note: The above separation is only true for Discovery system controllers. ++For Orion SoCs we stick to the separation, although there each controller has ++only one port associated.
