The same set of fields described for IPv6 ACL classification are also supported as match 
criteria for DiffServ classes. Prior to the introduction of IPv6 class rule fields, any layer 3 or 
layer 4 item was interpreted as a field in an IPv4 packet. To properly interpret the match 
criteria fields and create classifier entries, it is necessary for the configuration to specify what 
type of packet a class defines.
