I don't really know the lwip raw api regarding TCP. But what I know is that on socket-based systems, a TCP connection is only closed from one side if you call close(). It remains in a closing state until the other side has closed the connection, too. Without looking in the code, I would say this is the same for lwip raw api, too. I don't know if there is a function which aborts the connection without waiting for the other side to close it, too.
