[Bug 251540] [tcp] regression: no FIN on TCP connections when shutting down

--- Comment #1 from Michael Tuexen  ---
I just tested running a server

nc -l 8080

on FreeBSD head (r367530) against a client running nc 192.168.1.60 8080 and
then shutting down the host on which the server is running.

I'm also running tcpdump on the machine one which the client runs. I do see a
FIN segment sent by the server stack. When running the client using truss nc
192.168.1.60 8080 I can also see that the incoming FIN is processed, because
the reading end on the socket is shutdown.

Can you provide a reproducible setup where no FIN is sent?

^Triage:

- Assign to committer apparently resolving (please reassign if someone else)
- Assuming this is CURRENT (regression) only, if needs merging, set mfc-stable*
flags to (?) accordingly, until merged
