This is targeting 22.11 and includes the PMD for the

There is a dependency on that parallel serie still in-flight
which extends the bbdev api

I will be offline for a few weeks for the summer break but
Hernan will cover for me during that time if required.
Thanks

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.
I haven't seen your reply on this point.
Do you confirm you are working on a single driver for ACC family in
order to avoid code duplication?
Maxime
Thanks,
Maxime
