I've added those as well:

        int pcap_datalink_name_to_val(const char *name)

        const char *pcap_datalink_val_to_name(int dlt)

the first of which takes a DLT_ name (which is the part of the name
after DLT_, e.g. "EN10MB" and returns the DLT_ value (the lookup is
case-insensitive), or -1 if the lookup fails, and the second of which
takes a DLT_ value and returns the name, or NULL if the lookup fails.
