Indirect descriptors is a virtio feature that allows the driver to store a table of descriptors anywhere in memory, pointing to it from a virtqueue ring's descriptor with a particular flag. We can't seamlessly transition from an iterator over a conventional descriptor chain to an indirect chain, so Queue users need to explicitly support this feature by calling Queue::is_indirect() and Queue::new_from_indirect().
