How to get calling dissector

Hi all, TL,DR: How does a dissector know which dissector called it? Long version: I’m currently implementing a dissector for „Session Multiplex Protocol“ (SMP) [1] requested in bug 14110 [2]. The Tabular Data Stream (TDS; MS SQL Server) protocol depends on SMP when using the MARS feature [3]. SMP runs on top of TCP and is a session layer protocol. SMP however has no identifier to specify the next protocol. When TDS uses SMP the SMP payload itself is TDS. Resulting in dissector stack: Ethernet/IP/TCP/TDS/SMP/TDS. I want to call the TDS dissector for the SMP payload data only when it was called by TDS. Otherwise just display the data as hex. How can I get the information which dissector called my dissector? Any ideas are welcome. Thanks!
