Log:
Move the "guess what type of ATM traffic this is" stuff into the ATM
dissector; I don't think it's guaranteed that even a Sniffer will tell
you that (there may be situations where it can't figure it out, and
where the user didn't tell it), we may need it for "atmsnoop" traffic
and other types of ATM traffic as well, we will probably want to add to
it the ability to let the user specify "virtual circuit X.Y is this kind
of traffic", and we may also have Ethereal try to intuit it based on
previous traffic in the capture (Q.2931 call setup, LANE traffic, etc.).
Don't show the cell count if it's zero - assume that means we don't know
how many cells made up the packet. Also don't show the AAL5 trailer if
the cell count is zero - the ATM Sniffer *might* sometimes supply a cell
count of 0 even if it has the AAL5 trailer, I guess, and we *might* see
some other capture file format that has the AAL5 trailer but no cell
count, but we'll cross that bridge when we come to it.
Add support for "atmsnoop" captures to the code to handle "snoop"
captures.
Use the field in "iptrace" headers that appears to be, in ATM captures,
a direction indicator - we may have the direction backwards, but, as an
STP packet was tagged as a DCE->DTE packet, and as the capturing
machine, which also was presumably the recipient of the packet, was an
AIX box, not a switch or bridge or some piece of networking equipment
such as that, it *probably* wasn't sending the STP packet, it was
probably receiving it.
