Since we now have support for software CRC32c offload, turn it on for macvlan and macvtap devices so that guests can take advantage of offload SCTP checksums to the host or host hardware.

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

Adds a new tun offload flag to allow for SCTP checksum offload. The flag has to be set by the user and defaults to "no offload".

To support SCTP checksum offloading, we need to add a new feature to virtio_net, so we can negotiate support between the hypervisor and the guest. The signalling to the guest that an alternate checksum needs to be used is done via a new flag in the virtio_net_hdr. If the flag is set, the host will know to perform an alternate checksum calculation, which right now is only CRC32c. Signed-off-by:

To support SCTP checksum offloading, we need to add a new feature to virtio_net, so we can negotiate support between the hypervisor and the guest. The HOST feature bit signifies offloading support for transmit and enables device offload features. The GUEST feature bit signifies offloading support of recieve and is currently only used by the driver in case of xdp. That patch also adds an
