 Generate a deduplicated stream. Blocks which would have been sent multiple times in the send stream will only be sent once. The receiving system must also support this feature to receive a deduplicated stream.  This flag can be used regardless of the dataset's dedup  property, but performance will be much better if the filesystem uses a dedup-capable checksum (eg.  sha256).
