The Amazon Annapurna Labs PCIe Root Port exposes the VPD capability, but there is no actual support for it. Trying to access the VPD (for example, as part of lspci -vv or when reading the vpd sysfs file), results in the following warning print: pcieport 0001:00:00.0: VPD access failed. This is likely a firmware bug on this device.
