Napatech Software Suite: Extended NT descriptor IPF macros

Detailed Description

The following are used to help collect IP fragmented data. With theses macros it is possible to de-fragment IP fragmented data in a multi-processing application using 5-tuple hashing. It is only available if "PacketDescriptor" in the ntservice.ini file has been set to "Ext8" or "Ext9" and if NT_NET_GET_PKT_DESCRIPTOR_TYPE returns NT_PACKET_DESCRIPTOR_TYPE_NT_EXTENDED

Note
: These macros do not return valid values if the IPF engine is not turned on see IPFMode Command
