Fri 28 Oct 2011 11:21:14 AM UTC, comment #1: The state names are a direct representation of the TCP specification, so we won't remove or rename them. In lwIP, shutdown is seen as a rather "optional" feature, so the main focus is to keep normal closing bug-free, for which both the FIN-WAIT states are needed.

I propose to remove FIN_WAIT_2 state in TCP, because its a faulty feature.
