To override the value of the PCAP_FILTER variable in the fwknopd.conf config file, a new fwknopd command line argument "--pcap-filter" was added. This assists in various activities by making it trivial to change how fwknopd acquires packet data without editing the fwknopd.conf file. Here is an example: fwknopd -i lo -f --pcap-filter "udp port 12345"
