This is targeting 22.11 and includes the PMD for the integrated accelerator on Intel Xeon SPR-EEC. There is a dependency on that parallel serie still in-flight which extends the bbdev api https://patches.dpdk.org/project/dpdk/list/?series=23894 I will be offline for a few weeks for the summer break but Hernan will cover for me during that time if required.

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
