That's because there's no way to do that in Ethereal or tcpdump itself.

Perhaps somebody's constructed some way to start a capture program based
on a threshold such as that, e.g. a way to start a command if a network
traffic rate goes above a certain level.  If so, that could be used to
start tcpdump, Tethereal, or Ethereal (yes, you can start an Ethereal
capture from the command line - see the "-k" flag).

I don't of any such way myself, however.
