CONFIG_NET_TCP_TIME_WAIT:

Officially, the TCP standard requires a 4 minute timeout on connection close before that particular port pair can be used again. This requires that the net_context and net_tcp structs persist for the full duration, so has non-trivial memory costs and is optional. Modern systems with well-randomized sequence numbers don’t need this, but it is present for specification compliance where needed.
