I would be looking for the local adapter mac addresses.  Under linux
with pcap and the adapters I have, ethernet and wireless, I see
hardware mac addresses in pcap_if_t.addresses. I wasn't sure if there
were any known cases where pcap_if_t.addresses wouldn't have the
hardware mac address, like  with winpcap, particular devices etc.
Users have reported difficulty getting the adapter mac addresses so it
seemed useful to ask the experts.
