The ethernet frame is mostly formatted correctly. Just need to reverse the byte order in the Ethernet length/type field.

This is great. The FPGA is able to send ethernet frames consisting of the RVVI data to the host computer.
...
wireshark is able to capture the frames and they match the expected data!

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.

This commit does not include the source files for the ethernet as it does not belong to cvw.
I'll want to fork that repo and make it a submodule as I need to change the source a bit.

Yay. Finally found the issue with the integrated testbench.sv and imperasDV.
...
The function which loads the elf file rvviRefInit must be called during an initial block
using a valid file name. Because of how the testbench was organized the elffile was not defined
until several cycles later so the call to rvviRefInit did not have a valid elf. Waiting several
cycles does not work. rvviRefInit requires being called in an initial block so it is not possible
to run back to back imperasDV simulations in the same run.

This is crazy. I'm merging testbench.sv into testbench-imperas.sv to find the point when it stops working. But each logical point where it would stop working it keeps working. For example moving readmemh from initial to always block.
