NDIS LWF: how to get notified when a certain flow dies?

Let’s say you are interested in a certain flow, and you define that flow with a 5 tuple (srcIp, srcPort, dstIp, dstPort, Protocol)

My questions are:

  1. Let’s say a flow dies in a normal way, for example the other ends a RESET ACK packet, how to get notified of this, other than parsing the packets ourselves?

  2. How to get notified when a connection dies in a abnormal way, for example the other end loses connection due to cable problems, therefore doesn’t notify our end (server).
