FWIW, here was my attempt to solve the issue by making the PHY/MAC
layer selectable at run time, while preserving PHY as the default.

There was a fair amount of discussion, and it seemed to me that
everyone wanted a pony.

If anyone wants to take up that series, or present a more creative
solution, then by all means, please go ahead.  I still have a working
board with the PHYTER, and so I would be happy to help validate the
new feature.

Thanks,
Richard
