Frames that are processed are extracted from the datapath for CFM processing; unprocessed
frames are treated as user traffic and follow the user traffic rules.

Notes:
1. Tagged frames are single-tagged frames.
2. Untagged frames received on a dot1q encapsulated port are processed by the Epipe configured to handle
untagged frames. The SAP identifier on this Epipe uses VLAN ID 0, also referred to as SAP 0 (for example,
1/1/2:0).
