Thanks Todd for quick reply, Yes, we know the problem is on the PCIe port on the ARM is not allowing the VDM messages as you said the PCIe port should silently drop these messages if they are not supported, but its not doing so. We don't have anything on PCIe port to configure to drop these messages or some hardware problem on PCIe port on ARM side. If we know we can disable these VDM messages from the device side i.e, Intel I210 NIC.

I'm not sure, but the ARM hardware (or maybe it was the software) wasn't allowing the VDM that is allowed in the PCIe spec. Something on the motherboard side is non-compliant, not the Ethernet controller. I'd go check the arm mailing list. I'm pretty sure they had a workaround.

I am seeing similar problem what you were experiencing on this mailing list, where the bus master enable will cause the driver to hang Can you please let me know if you are able to resolve this issue on Intel I210. I have tried disabling Bus mastering after that its able to enumerate the pci devices but the driver does not get initialized becuase of the bus mastering. I was reading you previous mail threads on I210 where VDM messages being generated by this I210 Network device for NC-SI inband management. I have eeprom dump on X86 Linux OS. Can you please let me know how to disable this MCTP in ethernet EEPROM. I am using Intel I210 plug-in pcie card, which works @2.5GT/s and x1 linkwidth. Thanks in advance.
