"Above" as in "the link layer is 802.15.4, and the protocol
running atop 802.15.4 is the data layer"?
I.e., the "Data Payload" of an 802.15.4 Data frame is a Modbus
PDU of some sort?

That's because there's no Modbus dissector that registers itself
as being usable atop 802.15.4.
So are these Modbus RTU PDUs, beginning with a unit ID byte,
followed by a function code byte, followed by the data?
