Hi,

It would be useful to have an invisible field that lists the number of 
bytes, or a no-data flag.

When trying to analyse a trace recently, I wanted to mark no-data ACKs 
differently so I could ignore them or see the patters, and I found myself 
doing something like ip.len==40, which is not nice.

So, does anyone have any objections, or suggestions about what the field 
should be?
 
Regards
