All the passive stream identification functions (6.4, 6.5, 6.7, 6.8) have a statement along the lines of: “It discards the stream_handle subparameter passed down the stack.” For 6.6 Active Destination MAC and VLAN Stream identification such a statement is missing. It is unclear if it shall also discard the stream_handle on the down path (as suggested in 6.2: “The other SAP connects to the lower layers. This SAP can, but typically does not, include the stream_handle”) or not.
