This patch allows VIRTIO_NET_F_HASH_REPORT feature to the adapter whose backend does not have a virtio header and does not have offload features that depend on it. The migration between such different systems is very problematic even if it seems successful, such setups are not performance-oriented and especially supporting the hash delivery for them is (IMHO) redundant, it just requires more testing and does not bring any advantage.
Whether the peer has virtio headers or not is irrelevant if VIRTIO_NET_F_HASH_REPORT is offloaded or not. Currently QEMU always implements hash reporting by itself and does not offload at all.
