Usually the changelog should go after --- so it's not included in the
final commit message when merged. I hope in this case the maintainers
will take care of this manually so no need to resend unless they ask

Thank you for working on this. I'll be looking forward to your next
patch where response validation is added.

BTW, have you already discussed how exactly you plan to expose the
statistics to the userspace, is that something that should end up
visible via e.g. `ethtool -S eth0 --groups nc-si` ?
