I met below build errors in this patch when doing
per-patch build test with clang:
lib/librte_vhost/virtio_net.c:134:1: error: unused function 'flush_shadow_used_ring_packed'
[-Werror,-Wunused-function]
flush_shadow_used_ring_packed(struct virtio_net *dev,
^
lib/librte_vhost/virtio_net.c:188:1: error: unused function 'update_shadow_used_ring_packed'
[-Werror,-Wunused-function]
update_shadow_used_ring_packed(struct vhost_virtqueue *vq,
^
It's better to add __rte_unused in this patch,
and remove it when functions are used.
PS. I also saw similar errors with fill_vec_buf_packed()
in patch 11/15.
