bmips: add experimental ethernet support
This adds experimental ethernet support for BCM6318, BCM6328, BCM6362, BCM6368 and BCM63268. BCM6358 needs a different driver, so there's no support for now. Working devices: - Comtrend AR-5315u - Comtrend AR-5387un - Comtrend VR-3025u - Comtrend VR-3032u Not working devices: - Netgear DGND3700 v2 (no idea on how the external switch is connected) - Huawei HG556a ver B (BCM6358 needs a separate driveer) Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
