Follow-up Comment #2, bug #41700 (project lwip):
Already switched to tcp_listen in my code base. To save future developers some
grief, let's eliminate the edge case here. Having tcp_listen_dual check for
existing listeners on all relevant port/IP combinations sounds reasonable. I'd
further suggest that calls to tcp_listen_dual be atomic, so the caller doesn't
have to check after a successful call to ensure their PCBs are listening on
*all* of the desired port/IP combinations.
