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
