23# DESCRIPTION:
24#	Verify that 'zfs receive' produces an error when mixing
25#	raw and non-raw sends in a way that would break IV set
26#	consistency.
27#
28# STRATEGY:
29#	1. Create an initial dataset with 3 snapshots.
30#	2. Perform a raw send of the first snapshot to 2 other datasets.
31#	3. Perform a non-raw send of the second snapshot to one of
32#	   the other datasets. Perform a raw send from this dataset to
33#	   the last one.
34#	4. Attempt to raw send the final snapshot of the first dataset
35#	   to the other 2 datasets, which should fail.
36#	5. Repeat steps 1-4, but using bookmarks for incremental sends.
37#
