DirecTV DCAW1R1-01

Overview
This unit would seem to be a part of the (newer) DirecTV Cinema Connection Kit.

"48J7151C.SGE" and "2013/04/17" is silkscreened on the back of the WAVE300 Mini PCIe module in the FCC photos.

An unknown Marvell Ethernet chip is used.. it looks like 88E8020-NNC2, but there are no google results for the P/N.. possibly 88E8040-NNC2 (Yukon FE+)?
