At line 56 of packet-netflow.c, it says that:

 ** this code was written from the following documentation:
 **
 **
http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/nfc/nfc_3_6/iug/format.pdf
 **
http://www.caida.org/tools/measurement/cflowd/configuration/configuration-9.html

If I'm reading that first document correctly, it would seem that all versions
of netflow prior to v9 used 2 bytes for those fields, not 4.  Given that, I'm
not sure this patch will work correctly for netflow packets prior to v9.
