10.4.15 SGSN-INVOKE-TRACE
This PDU indicates that the BSS shall begin the production of a trace record
for an MS.
PDU type: SGSN-INVOKE-TRACE
Direction: SGSN to BSS
Table 10.4.15: SGSN-INVOKE-TRACE PDU content
--------------------------------------------------
|Information elements | Type / Reference       |...
|---------------------|------------------------|--
|  PDU type           | PDU type/11.3.26       |...
|---------------------|------------------------|--
|  Trace Type         | Trace Type/11.3.38     |...
|---------------------|------------------------|--
|  Trace Reference    | Trace Reference/11.3.37|...
|---------------------|------------------------|--
|   ...               |  .........             |
--------------------------------------------------------------------
/* Trace Type Trace Type/11.3.38 M TLV 3 */
    ELEM_MAND_TELV(0x22, BSSGP_PDU_TYPE, DE_BSSGP_BVCI , NULL);

So.I think the should be:

/* Trace Type Trace Type/11.3.38 M TLV 3 */
    ELEM_MAND_TELV(0x22, BSSGP_PDU_TYPE, DE_BSSGP_TRACE_TYPE , NULL);
