System: NetBSD avernus 1.5_ALPHA2 NetBSD 1.5_ALPHA2 (AVERNUS) #0: Sun Aug 27 15:29:49 PDT 2000 root@avernus:/usr/src/sys/arch/i386/compile/AVERNUS i386


>Description:
The NetBSD specific PPP types in /usr/include/net/bpf.h:

/* NetBSD-specific types */
#define DLT_PPP_SERIAL  50      /* PPP over serial (async and sync) */
#define DLT_PPP_ETHER   51      /* PPP over Ethernet */

aren't supported by the ethereal package because the values are used as
an index into the pcap_encap lookup table and it doesn't extend that far.

>How-To-Repeat:
Install the ethereal package and try to capture packets on a PPP interface.
It complains that
    "The network you're capturing from is of a type that Ethereal doesn't support."

>Fix:
A bit ugly I suppose, but it fits the current coding model. Only tested on
serial line PPP.
