# Description:
# Verify resumability of an incremental ZFS send/receive with ZFS bookmarks in
# the presence of a corrupted stream.
#
# Strategy:
# 1. Bookmark a ZFS snapshot
# 2. Destroy the ZFS sanpshot
# 3. Destroy the filesystem for the receive
# 4. Verify receive of the full send stream
# 5. Start an incremental ZFS send of the ZFS bookmark, redirect output to a
#    file
# 6. Mess up the contents of the stream state file on disk
# 7. Try ZFS receive, which should fail with a checksum mismatch error
# 8. ZFS send to the stream state file again using the receive_resume_token
# 9. ZFS receieve and verify the receive completes successfully
