#    This sample creates two IPv4 stream with increasing frame length, one     #
#    having bad CRC errors.                                                    #
#    The trigger is set to bad CRC and the filter is set to a framesize range  #
#    uds1 is set to count frames with bad CRC, uds2 is set to count good       #
#    frames and uds5 (async_trigger1) is set to count all packets              #
#    Starts the capture then it starts the streams, collects statistics and    #
#    returns the capture buffer in the default filename.                       #
#                                                                              #
