We currently don't have justifications for the per queue stats,
hence we will move it out of the series at this point. We might
reconsider it in the future.

We'll continue with your suggestion with global dynamic strings to
avoid having the need to update ethtool with the additional counters
we are planning to add as part of the incremental features (TX, target
mode, ...).

Thanks
