Libpcap is putting a DLT type of 6 in the capture file, which is IEEE802,
which on other platforms is used to denote token-ring (802.5).
On non-AIX platforms, a DLT type of 1 is used for ethernet.

Let me download the libpcap source to dig into that.

Using AIX's native, hacked tcpdump, with the -w option, can you
correctly read those capture files with ethereal. That is, do they
come up as ethernet?
