Actually what exactly happens after calling SendPacketToAdapter or SendPacketToMstcp it will remove from the adapter queue or not also if i call FlushAdapterPacketQueue which packets will be clear exactly means the packets which are in queue or some other means new packets?
SendPacketToAdapter and SendPacketToMstcp don’t affect adapter packet queue, but ReadPacket does. The packet is added to the queue when it comes from the MSTCP or from the network and removed from the queue when you read it.
