>Description:
/usr/include/net/bpf.h has bad comment about DLT_NULL.
It is not true that this type is  /* no link-layer encapsulation */
this type is BSD loopback encapsulation; the link layer header is a 4-byte
field (see man pcap), so please correct this comment. 
	
>How-To-Repeat:
>Fix:
#define DLT_NULL        0       /* BSD loopback encapsulation */
