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.
