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 (skb->csum_not_inet) to determine whether to use standard inet checksum or the SCTP CRC32c checksum. This bit has to be communicated between the host and the guest. This bit is carried in the vnet header....
