Solution
The data link layer frame does not include the "Source Port". This is typically found in the Transport layer, not the Data Link layer. The Data Link layer is primarily concerned with physical addressing, line discipline, network topology, error notification, ordered delivery of frames, and control of congestion. The Source Port is used in the Transport layer to identify the sending and receiving applications or processes.
