    netpfil tests: skip checksum verification in pft_ping.py
    
    From scapy 2.6.0 it now removes (sets to None) the IP checksum in its defrag
    code. We typically ask for IPv4 or IPv6 defragmentation, which causes check
    function failures.
    
    Just skip the checksum verificiation here, because we're going to notice
    incorrect checksums even if the tests don't directly verify it.
