The problem is the pcap library, not the source of the program. Before sending any patches I think I need familiarize myself with libpcap more. Because it's pretty scary to patch program which has comments like this: * Back in 2002, Donald Lee at Cray wanted a DLT_ for * IP-over-FC: [skip] * 11 years later, Christian Svensson wanted to map * various ARPHRD_ values to DLT_FC_2 and * DLT_FC_2_WITH_FRAME_DELIMS for raw Fibre Channel * frames: One more question: no radiotap headers currently can be injected. Right? The underlie levels just ignore DLT_IEEE802_11_RADIO dlt.
