Re: Should we have "Window size scaling factor: -1 (unknown)" in the packet details, or just leave the scaling factor out?

Me too... but of course I do, as I introduced it :-)

I like that idea. Should we completely drop the output of the field value when it is -1 or -2 and let users figure out 
the value for themselves when using "Apply as filter"? This would result in:

"Window size scaling factor: unknown, start of session not captured"
"Window size scaling factor: no window scaling used"

Or would it be better to include the artificial value:

"Window size scaling factor: -1 (unknown, start of session not captured)"
"Window size scaling factor: -2 (no window scaling used)"

Or maybe like this:

"Window size scaling factor: unknown, start of session not captured (-1)"
"Window size scaling factor: no window scaling used (-2)"

I tend to like the first option best as it does not confuse the user with a fabricated value. People that want to use 
this as a filter will find out the value by using any of the  "... as filter" options.

Any objections?

Cheers,
Sake
