- Time to wait for logical port negotiation (in ms). If a logical port is under negotiation, it waits for the
negotiation to finish up to this timeout before trying to send a message to that port. Setting this option to
non-zero values increases the discovery time. Setting it to zero means no wait but could lead to loss of first
messages.
