For the Gen3 Integrated Block for PCIe v3.0 (PG023 December 18, 2013 and previous versions) the user guide reads, "
MSI-X Interrupts need to be generated by the User Application and presented on the transmit AXI4-Stream interface." (page 166) This is most likely incorrect and may be left over from a much earlier datasheet (485T perhaps?).
There is a dedicated MSI/MSI-X interface so this is no longer needed.
