5 minutes delay for delivery report.

Hi team, we are using node-rdkafka. During the network test, we always get error delivery-report callback after 5 minutes when our system got a network failure. We have tried to reduce the timeout parameters value (delivery.timeout.ms). But It was not working. Could you please give some guide to reduce the delay of the 'delivery-report' event callback?

Start by reproducing the delivery-report callback behavior during a network failure in node-rdkafka, then inspect how delivery.timeout.ms is passed to and handled by the underlying librdkafka binding. Confirm the actual callback timing and identify whether the documented configuration affects this failure path; done means a verified explanation or a focused fix with regression coverage.
