There is no such variable.

You would have to maintain that information yourself.

Note also that, when dissecting the packet at x, you do not have any
access to information about later packets during the first pass through
the capture file.  That is the *only* pass in Tethereal; in Ethereal,
that information would be available (if you maintained it yourself) when
the packet is, for example, clicked on, or when doing a "print" pass.
