OpenZFS-issue: https://www.illumos.org/issues/7247
OpenZFS-commit: https://github.com/openzfs/openzfs/commit/2ad25b4
Closes #5689 

Porting notes:
- tests/zfs-tests/tests/functional/cli_root/zfs_receive/zfs_receive_013_pos.ksh
  renamed as zfs_receive_015_pos.ksh, zfs_receive_013_pos.ksh is now
  used for OpenZFS test.
- libzfs_sendrecv.c: SMALLEST_POSSIBLE_MAX_DDT_MB is always used
  for all 32-bit builds.

 # DESCRIPTION:
-#	Verify ZFS can receive custom properties on both filesystems and
-#	snapshots from full and incremental streams.
+#   Verifying 'zfs receive' works correctly on deduplicated streams
 #
 # STRATEGY:
-#	1. Create a filesystem.
-#	2. Snapshot the filesystem.
-#	3. Set custom properties on both the fs and snapshots.
-#	4. Create different send streams with the properties.
-#	5. Receive the send streams and verify the properties.
+#   1. Create some snapshots with duplicated data
+#   2. Send a deduplicated stream of the last snapshot
+#   3. Attempt to receive the deduplicated stream
