1. A method for communicating a sequence of media access control (MAC) service data units (MSDUs) that make up a traffic stream from a first station (STA) to a second STA over an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network, the method comprising:
transmitting, by the first STA to the second STA, a first MAC protocol data unit (MPDU) payload over a first 802.11 link; and
transmitting, by the first STA to the second STA, a second MPDU payload over a second 802.11 link that is different than the first 802.11 link, a first MSDU segment in the sequence of MSDUs being encapsulated within the first MPDU payload, and a second MSDU segment in the sequence of MSDUs being encapsulated within the second MPDU payload,
wherein a first MAC header appended to the first MPDU payload includes transmitter (TX) and receiver (RX) MAC addresses that are specific to the first 802.11 link, a first sequence control field that identifies a first location of the first MSDU segment within the sequence of MSDUs,
wherein a second MAC header appended to the second MPDU payload includes TX and RX MAC addresses that are specific to the second 802.11 link and a second sequence control field that identifies a second location of the second MSDU segment within the sequence of MSDUs,
wherein each of the first sequence control field and the second sequence control field further includes a corresponding fragment number indicating whether each of the first MSDU segment and the second MSDU segment is an unfragmented MSDU,
wherein the first sequence control field and the second sequence control field include the same sequence number to indicate that the first MSDU segment and the second MSDU segment correspond to a common MSDU within the sequence of MSDUs, and
wherein corresponding fragment numbers included in the first sequence control field and the second sequence control field have the same value indicating that the first MSDU segment and the second MSDU segment are a same MSDU fragment of the common MSDU.
