This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The driver uses interrupts to handle received frames, but it uses a spinloop when transmitting to wait for the transmit descriptor to become available. Transmission is coordinated by a fiber, so this should not result in the system execution being blocked. Only a single descriptor is allocated for each of the transmit and receive directions to save memory and simplify the code. Another simplification is that none of the offload capabilities of the Ethernet device are used. The driver currently only supports a single instance of the Ethernet MAC, which is consistent with the limitation in the network stack that only a single network device is supported.
