During the RFC, I mentioned that I will split out the series after
initial feedback. So the RFC (after incorporating the feedback) was split
into:
1. This series (v1)
2. Changes for net-next (v1 and v2 have been sent out):
https://lore.kernel.org/netdev/20260908-shikra_ethernet-v2-0-bbe3389d0652@xxxxxxxxxxxxxxxx/

This particular commit message needs to be rewritten as its not breaking
anything in the current tree. I will fix that and drop the Fixes: tag.
