7.3 LOGICAL PROCESSING FUNCTIONS FOR ETHERNET PAYLOAD
The description of Ethernet processing in the present document is made using a set of logical blocks that
represent the processing stages of a frame entering the L2 switch (it is intended to be just logical; it does
not represent the structure of the physical implementation).

From left to right the pocket processing is represented from Ingress to Egress.
