Setting TCP_LISTEN_BACKLOG==0 means "disabled". In this case, backlog is
limited by the number of PCBs.

In lwIP, the listen backlog is the number of incoming connections queued for
accept(), meaning once you accepted one connection, another one is free to be
queued for the next accept call. Open client connections previously accepted do
not count in here.
