Add driver for DM&P Vortex86 RDC R6040 Fast Ethernet.
The controller is commonly found on DM&P Vortex86 x86 SoC. The
driver supports all hardware features except flow control. The
flow control was intentionally disabled due to silicon bug.

DM&P Electronics, Inc. provided all necessary information including
sample board to write driver and answered many questions I had.
Many thanks for their support of FreeBSD.
