This allows support of TC protocol all for the Sparx5 IS2 VCAP. This is done by creating multiple rules that covers the rule size and traffic types in the IS2. Each rule size (e.g X16 and X6) may have multiple keysets and if there are more than one the type field in the VCAP rule will be wildcarded to support these keysets.
