This patch series was extracted from: https://lore.kernel.org/qemu-devel/20250313-hash-v4-0-c75c494b4...@daynix.com/ ("[PATCH RFC v4 00/11] virtio-net: Offload hashing without eBPF")
According to the specification, virtio-net devices with VIRTIO_NET_F_RSS or VIRTIO_NET_F_HASH_REPORT can report supported hash types: https://docs.oasis-open.org/virtio/virtio/v1.2/csd01/virtio-v1.2-csd01.html#x1-2230004 vDPA also implements the same functionality, but QEMU currently does not respect it. Ensure that the vDPA device satisfies the requirements of the VM by checking the supported hash types. This also helps add another hashing mechanism proposed by the patch series mentioned earlier.
