To be specific: * Hardware supports source validation but it will report the issue as Completer Abort instead of ACS Violation. * Hardware doesn't support peer-to-peer and each root port is a root complex with unique segment numbers. * It is not possible for one root port to pass traffic to the other root port. All PCIe transactions are terminated inside the root port. Add an ACS quirk for the QDF2400 and QDF2432 products.
