This series adds support for the Frame DMA present on the VSC7514 switch. The FDMA is able to extract and inject packets on the various ethernet interfaces present on the switch. While adding FDMA support, bindings were switched from .txt to .yaml and mac address read from device-tree was added to allow be set instead of using random mac address.
