I guess this patch needs better testing; the above triggers a compile
warning:
./drivers/vhost/net.c:81:2: warning: excess elements in array
initializer [-Wexcess-initializers]
81 | VIRTIO_BIT(VIRTIO_NET_F_OUT_NET_HEADER),
which in turns hints the feature is not actually used/available. The
chunk should be:
VIRTIO_BIT(VIRTIO_NET_F_GUEST_UDP_TUNNEL_GSO) |
VIRTIO_BIT(VIRTIO_NET_F_HOST_UDP_TUNNEL_GSO) |
VIRTIO_BIT(VIRTIO_NET_F_OUT_NET_HEADER),
/P
