U can use both the information!! for example if the packet contains fragment offset > 0, then definitely its a fragmented packet. Also if the packet contains fragment offset = 0, and if the 'MF' flag is set to '1' it is again a fragmented packet. Finally unfragmented datagram has all zero fragmentation information (MF = 0, fragment offset = 0).
