Suggestions for extra libpcap functions

[Darren Reed <darrenr () reed wattle id au>]

How about these:

int pcap_llheadersize(int dlt)
int pcap_get_datalink(pcap_t *pd)

Typical use might be:

        int skipbytes;

        skipbytes = pcap_llheadersize(pcap_get_datalink(pd));

I find it frustrating that every application I write to handle libpcap
input needs the above functions written, in one way or another.
