This patch introduces an ioctl way to set an offloaded XDP program
to tun driver. This ioctl will be used by qemu to offload XDP program
from virtio_net in the guest.
Seems like you need to set / reset the SOCK_XDP flag on tfile->sk since
this is an XDP program.
Also, why not add this program using netlink instead of ioctl? e.g., as
part of a generic XDP in the egress path like I am looking into for the
host side.
Maybe both, otherwise, qemu may need netlink as a dependency.
Thanks
