I'm not that familiar with netflow data, but from a quick look and
your question I'm guessing that it has packets buried in there. If
that is the case and you want Snort to read the packets and process
them as if it were a pcap, then you can either:

1. Export a pcap from netflow data (there may be a tool for that).
2. Write a netflow DAQ.
