Use pcap_open() and open with the PCAP_OPENFLAG_MAX_RESPONSIVENESS flag:


The libpcap equivalent is to use pcap_create() and pcap_activate() and, between the pcap_create() and pcap_activate() calls, call

	pcap_set_immediate_mode(handle, 1);

in libpcap 1.5 and later (or to set immediate mode in a platform-dependent fashion in previous releases).
