weird that lspci does not know about PciCfg wanna patch that?

So they didn't set subsystem id and we can't identify the device for
a quirk. Not nice. And sadly I do not see anything here that will
let us identify the specific hardware with any kind of robustness.
Waiting for you to report whether the device can be fixed in the field with
some kind of firmware update.
