That's just one way.  You do not need TSNs.  As you are expecting an LSR
and have not yet received one, all that you need to is wait for a timeout
period for an LSR on stream 0, after which you can process the DATA (SLTM).

This will result in processing of missing LPSs before the DATA and is purely
a local procedure at the receiver that is in accordance with RFC 4165/4.1.8.
