Hi,
It seems this patch has been forgotten for a while but it is still
valid. Can anyone take a look at this?

The documentation used to say:
For example,
pci=config_acs=10x
would configure all devices that support ACS to enable P2P Request
Redirect, disable Translation Blocking, and leave Source Validation
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.
