Research direction
Start with the sendpack test demo and the pcap_sendpacket failure described in the report. Compare behavior with Npcap 1.79, 1.80, and 1.60 while checking Wireshark captures and whether response packets can be received. Done means the environment-specific send and receive behavior is reproduced and its cause or resolution is documented.
