The documentation used to say:

> unchanged from whatever power-up or firmware set it to.

However, a flag specification always needs to be suffixed with "@" and a
PCI device string, which is missing in this example. It needs to be
suffixed with "@pci:0:0" to configure all devices that support ACS in
particular.
