In this section
This section describes a change to the NtNetBuf_s structure in the include/ntapi/stream_net.h file.
The length parameter has changed from an uint32_t type in Green Bay 2 to an uint64_t type for 4GA SmartNICs in Link™ Capture Software 12.1 to accommodate for the larger buffer size.
The NTAPI_VERSION definition in the include/ntapi/version.h file has changed from 1 in Green Bay 2 to 2 for 4GA SmartNICs in Link™ Capture Software 12.1 because the change in NtNetBuf_s requires that applications are recompiled.
Due to the changes application code will need to be recompiled, and tools/applications from earlier driver releases will no longer work. If the NtNetBuf_s structure is accessed directly from application code (not utilizing the provided macros), updates to the application code might be needed.
