+# DESCRIPTION:
+# Verify 'zfs receive -x' consistently excludes a property across
+# incremental sends with -p, and does not alternate.
+#
+# STRATEGY:
+# 1. Create source and destination datasets.
+# 2. Set a native property (refquota) on source.
+# 3. Full send with -p, receive with -x refquota.
+# 4. Verify refquota is not set on destination.
+# 5. Loop several incremental sends/receives with -p/-x.
+# 6. Each iteration verify refquota stays consistently excluded.
