Stratix 10 PCIe SR-IOV

Hi All, I am using the PCIe SR-IOV IP for Stratix 10. I see that Virtual Functions default to a Maximum Read Request and Max Payload Size of 128B. Is this a limitation of the actual specification ?...

Hi,


I apologize for the confusion. There is no max payload size setting specifically for the VF. As per the PCIe spec, the max payload size in the PF device control register setting applies to the VF. Do you able to send the same payload size (for example 512 bytes) for both PF and VF (under the same PF)?
