I would like to request a change in the output of -z io,stat of tshark, so that
it provides measurements as they've been requested into a simple .csv format.
This would make automated/scripted use of the command much easier than the
ASCII text output that it presents now.

One difficulty with the current format is that, while all stats are held to a
single line of text, it is not a fixed line number of the output (ie: adding
another counter means that the output will produce one more line before the
line containing all the measurements).

Another difficulty is that frames and bytes in some measurement types are
presented and delimited separately whereas other measurement types give only
one return column (eg: AVG() or MIN() functions), requiring a script to know
how many column returns result from what types of measurements, reading the
header information in the output to do all the correlation.

A simple .csv output where all returns are a single delimited value would, I
believe, make many people's lives easier here.
