>Description:

	5.1 includes support for the libpcap APIs to get a list of DLT_
	values supported by a device and to set the DLT_ value to be
	used, at least from looking at the CVS information for the
	libpcap source.

	However, it doesn't include the "pcap_datalink_name_to_val()"
	and "pcap_datalink_val_to_name()" APIs from tcpdump.org libpcap
	to map DLT_ names to values and vice versa (e.g., DLT_EN10MB <->
	"EN10MB"), for use by programs such as tcpdump and Tethereal.

>How-To-Repeat:

	See the CVS source.

>Fix:
	
	Pick them up from tcpdump.org's libpcap.
