This revision introduces basic support for the internal ESW switch found Ralink/Mediatek SoCs such as RT3050, RT3352, RT5350, MT7628; and GSW found in MT7620 and MT7621. It only supports 802.1q VLANs and doesn't support external PHYs at the moment (only the ones that are built into the switch itself).
