I played around a bit with this. Turned out that no matter where I
placed the code in this function, it didn't have any effect. Then I
grep'ed the code for other socket() calls and found the only other
I replicated the code there and now all packets leave the server with
the DF bit cleared (works for both replies and self-initiated messages).
