Unfortunately, it's not "my script" - it's just one I happen to have found that
exercises the TCP-reassembly stuff. (found on
https://github.com/diegonc/packet-bnetp)

I only mention that it's not mine because there could be any number of such Lua
scripts out there that do something similar - since it worked in previous
releases.

Right I figured, but I don't see why it's an error.  I'll comment on that
separately.
