Could someone provide a good documentation / tutorial/ PDFs/ reference to book link about Net::Pcap in addtion to the module documentation and this Perl and Net::Pcap article on PerlMonks?

A: 

If you just want a callback for every TCP/UDP/etc. packet matching a filter, you might find Net::Pcap::Easy more convenient. You can man tcpdump for documentation on libpcap filter strings.
