Enable this option to classify ingress traffic based on 802.1p, DiffServ, or both.

This mechanism classifies traffic based on the value of the VLAN priority field present within

DiffServ (Differentiated Services)

This mechanism classifies traffic based on the value of the Differentiated Services (DS)
codepoint field in IPv4 and IPv6 packet headers (as defined in RFC2474). The codepoint is
composed of the six most significant bits of the DS field.
