There's no need to do header check for virtio-net since: - Host sets dodgy for all gso packets from guest and check the header. - Host should be prepared for all kinds of evil packets from guest, since malicious guest can send any kinds of packet. So this patch sets NETIF_F_GSO_ROBUST for virtio-net to skip the check. Cc: Rusty Russell <rusty@xxxxxxxxxxxxxxx> Cc: Michael S. Tsirkin <mst@xxxxxxxxxx> Acked-by: Michael S.
