Plan for 10/100 Ethernet support for umTRX

The Ettus UHD framework adopted for the umTRX only supports GigE (simple_gemac). A reworked, Wishbone-compliant 10/100 Ethernet MAC is included in the OpenRISC SoC project on Opencores. It has been ported to the Digilent Atlys board, which has a Spartan-6 FPGA.

I'll begin the port of this Ethernet MAC (a cleaned-up version of the 10/100 core on OpenCores) to the UmTRX and test it on Close-Haul's SP-605 Spartan-6 eval. board. I'm not quite sure how long this task will take, but this feature falls into the "nice-to-have-but-not-urgent" category.
