When opening Netflow v5 packets (captured on UDP port 2055), Wireshark and
Tshark report these as malformed WCCP packets. The CFLOW configuration does
have it looking for Netflow packets on UDP port 2055, as default.

Only when WCCP is disabled as a decoded protocol does wireshark decode
correctly as CFLOW. ("Decode as" when configured for CFLOW on UDP dest port
2055 does not override this).
