Have rvvi to ethernet working.
...
Now it is time to move the hardware to the FPGA.
Ideally I don't want Wally to actually have any of this code since it's entirely
debug code so it will move to the fpga/src directory.
Then we'll need to add additional logic to the mmcm to generate the correct clocks.
Finally we'll update the I/O to add ethernet.
