Back in Wireshark 1.2.2, the attached file was not recognised at all as a valid
Sun Snoop file. At least with the latest SVN version that I have tested
(1.3.3-SVN-31499), the file is correctly recognised as a Sun Snoop file;
although many the frames within are considered malformed, and are not dissected
correctly.
I'm not too certain about what the end result should look like as far as
headers are concerned, although I know that it at least contains SMB, mDNS, and
RLogin packets. Unusually, it seems that pieces of text from various packets
are being used as the source of garbage data length values within the IPNet
headers.

However, it seems that another Snoop Loopback capture file that I found
elsewhere is parsed correctly. I can provide that file, if necessary.
