Now that we have SCTP offload capabilities in the kernel, we can add them to virtio as well. First step is SCTP checksum. We need a new freature in virtio to negotiate this support since SCTP is excluded with the stardard checksum and requires a little bit extra. This series proposes VIRTIO_NET_F_SCTP_CSUM feature bit. As the "little bit extra", the kernel uses a new bit in the skb
