with a similarly named similar alternative, the script itself is fairly
simple as scapy is used to do much of the work.

Pcapdiff is a tool developed by the EFF to compare two packet captures
and identify potentially forged, dropped, or mangled packets.
Two technically-inclined friends can set up packet captures on their
own computers and produce network traffic between their two computers
over the Internet.
Later, they can run pcapdiff on the two packet capture files to
identify suspicious packets for further investigation.
pcap_diff.py is a tool that takes two or more pcap files as input,
compares them, and produces a pcap file or displays to show differences
between the two. It is useful when comparing packets captured at two
points to identify interference with packets. It has options to ignore
certain parts of the packet (by default ttl, checksums and timestamps
are ignored).
