Based-on: <20240915-queue-v1-0-b49bd49b926d@daynix.com>
("[PATCH 0/7] virtio-net fixes")

I'm proposing to add a feature to offload virtio-net RSS/hash report to
Linux. This series contain patches to utilize the proposed Linux feature.
The patches for Linux are available at:
https://lore.kernel.org/r/20240915-rss-v3-0-c630015db082@daynix.com/

This work will be presented at LPC 2024:
