Comparing ACC200 & ACC100 header files, I understand ACC200 is an
evolution of the ACC10x family. The FEC bits are really close, ACC200
main addition seems to be FFT acceleration which could be handled in
ACC10x driver based on device ID.

I think both drivers have to be merged in order to avoid code
duplication. That's how other families of devices (e.g. i40e) are
handled.

Thanks,
Maxime
