My apologies.

Yes, I really do know that UDP has nothing to do with TCP. What I meant with my
question for "skipping the RST" was that:
In file tcp_in.c, around lines 407-416 (tcp_input) is else-branch with comment
"/* If no matching PCB was found, send a TCP RST (reset) to the sender. */" has
code which sends the TCP RST in this case.
I was thinking that I could "simply" free the pbuf and not call the tcp_rst
here, but there are probably reasons why PCB wouldn't be available other than
"No TCP available in this port"?
Anyway I'm not making such modifications unless I really have to.
