# Description:
# Verify that a partially received dataset can be sent with
# 'zfs send --saved'.
#
# Strategy:
# 1. Setup a pool with partially received filesystem
# 2. Perform saved send without incremental
# 3. Perform saved send with incremental
# 4. Perform saved send with incremental, resuming from a token
# 5. Perform negative tests for invalid command inputs
