[PATCH net-next] virtio-net: don't do header check for dodgy gso packets
There's no need to do header check for virito-net since: - Host set dodgy for all gso packets from guest and check the header. - Host should prepare 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 at rustcorp.com.au> Cc: Michael S.

[PATCH V2 net-next 0/6] virtio-net: Add SCTP checksum offload support
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
