21# Description:
22# Verify a pool without the lz4 feature gracefully rejects a compressed stream
23# because on any sending pool that supports it, metadata will be compressed
24# with lz4 even if user data is not compressed.
25#
26# Strategy:
27# 1. For each of an uncompressed, gzip and lz4 dataset, do the following
28#    receives into a pool without the lz4 feature:
29# 2. Attempt to receive the compressed stream (should fail)
30# 3. Attempt to receive the uncompressed stream (should succeed)
