Encapsulation for link layer preemption

Devices implement encapsulation to support link layer preemption. The device may include a encapsulation logic that encapsulates data, such as an Ethernet frame, to produce an encapsulated frame. The encapsulated frame may include an encapsulation element that indicates whether the encapsulated data includes non-preemptible data, such as Distinguished Minimum Latency Traffic (DMLT), or preemptible data. The encapsulated frame may also indicate whether the encapsulated data comprises the last fragment of a preemptible frame.
