Merge branch 'pci/enumeration'
- Work around IDT switch ACS Source Validation erratum (James Puthukattukaran) - Emit diagnostics for all cases of PCIe Link downtraining (Links operating slower than they're capable of) (Alexandru Gagniuc) - Skip VFs when configuring Max Payload Size (Myron Stowe) - Reduce Root Port Max Payload Size if necessary when hot-adding a device below it (Myron Stowe) * pci/enumeration: PCI: Match Root Port's MPS to endpoint's MPSS as necessary PCI: Skip MPS logic for Virtual Functions (VFs) PCI: Check for PCIe Link downtraining PCI: Workaround IDT switch ACS Source Validation erratum
