Is there an option: only_summaries in Scapy?

I am processing a huge pcap file by Scapy, but it's slow. When I am planning refactoring it by Pyshark, I found that there is an function named 'pyshark.FileCapture()' which offers a option: only_summaries. That's what I want. So, is there any option or method in Scapy too?
