This, of course, doesn't help if you didn't capture the connection setup; it's
useful, but insufficient.

I'm also not sure how the "minimum segment size" affects things here.  Is the
"minimum segment size" a value used by heuristic dissectors, i.e. the minimum
amount of data necessary to see whether the data in a TCP stream is for the
protocol in question?  Or is it the "fixed_len" argument to tcp_dissect_pdus(),
which is *not* a minimum segment size - if tcp_dissect_pdus() doesn't
reassemble smaller segments as necessary to get that amount of data, that's a
bug, as it means that it's not doing enough reassembly?
