This driver implements MAC and MII layer of the ethernet controller. Network data transfer is handled by controller internal DMA engine. Ethernet controller is configurable through device-tree file.

Why using these helper functions instead of directly? Yes, we may be casting in some cases and if that's how it must be, so be it (it's how we're doing it in other drivers). Thanks!
