Netflow dissector epan/dissector/packet-netflow.c
cannot decode correctly the Netflow v9 Options, because it does not take into
account the option scope of the option template.
Options are used by Cisco IOS, IOS-XR and Huawei VRP to report the sampling
rate, the ifName and ifDescr of the interfaces.
So I propose a patch that:
- decodes options correctly
- adds a few Netflow v9 types, as found in Cisco Flexible Netflow IOS 12.4T
- prints the unknown netflow types in hexa (useful for tshark)
