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. Contact the card vendor for a firmware update
