Gets packets/segments from a file stream.
This function is called to retrieve packets or segments from a capture file
This function has no mutex protection, therefore the same hStream cannot be used by multiple threads
When NT_STATUS_END_OF_FILE is returned the internal file offset that been reset making it possible to call NT_NetFileGet() again without having to close and open the file, which improves performance when replaying a file continuously.
NetFile stream handle
Packet/segment container reference
EOF indicator - See note
