Name	Type	Description
PcpTrafficClassClassifier	compound module	This module classifies packets based on the attached PCP value [0, 7]. The PCP is determined by a PcpReq or a PcpInd or both. The output gate index is the value found in the mapping matrix using the PCP value as the row index and the number of connected consumers (traffic categories) as the column index.
