> 
> The crypto backend uses RTE_VHOST_USER_DEQUEUE_ZERO_COPY only
> for the shared areas to be populated at mmap time. It does
> not use the other mechanisms the feature provides.
> 
> Now that RTE_VHOST_USER_DEQUEUE_ZERO_COPY is being removed,
> let's use RTE_VHOST_USER_ASYNC_COPY instead which does the
> same thing.
