====================
dwc_eth_qos: Add support for Synopsys DWC Ethernet QoS

This is a driver supporting version 4.10a of the Synopsys DWC Ethernet QoS
gigabit ethernet controller. The IP has changed significantly compared to the
dwmac1000 so a separate driver is justified.

The IP is highly configurable at synthesis time. This driver has been
developed for a subset of the total available feature set. Currently
it supports:
* TSO
* Checksum offload for RX and TX.
* Energy efficient ethernet.
* GMII phy interface.
* The statistics module.
* Single RX and TX queue.
