That's not a problem, Kbuild is smart enough to drop duplicate object files
that get built into the same module.

If you think it's less confusing to readers of this file if it gets
put into core,
that's fine though, the only downside would be adding a little bit of
code bloat for users that want neither the ethernet nor the fpga code
(if that is a realistic use case).
