It's the sender that has this limit. As in your example, lwIP is the receiver,
slow start doesn't help you.
Also, what you are talking about is actually a limit to the window, not to
the maximum segment size. Being like that, 1460 is NOT the upper limit.
Again, without having the remote side under control, you can NOT ensure to
get 512 byte sized segments. That's just not what TCP is like.
