I'm looking for a display filter that will count the number of duplicate packets.

1) What is your definition of a "duplicate packet"? Same frame content? Same IP identifier for IP packets?

2) Display filters do not have any state - they just test various fields in the packet or calculated by dissectors for the packet - and don't count things, so a display filter couldn't do this; another mechanism would have to be used.
