I.e., you don't know the format of the .stk files yet?

So is there more than one .stk file per .rf5 file?

And are the .stk files written by users, by the K12xx, or by Tektronix 
(with a fixed set of .stk files)?

Ethereal - including Wiretap - now require support for int64 and uint64, 
so you can just use those.  *Printing* them requires some work, but look 
for PRIu64 in packet-rsvp.c for an example of how to handle that.
