How to send multi vector msi interrupt packet?

Hi,

We are trying to send msi multi vector interrupt from FPGA endpoint to Jetson AGX Xavier. When we send the msi packet with data 0, vector 0 interrupt handler invoked. But, when we send msi packet with data 1, vector 0 interrupt handler is only getting invoked. How to send msi interrupt packet to invoke vector 1 interrupt handler?
