Merge branch 'pci/virtualization'
- add generic enable function for simple SR-IOV hardware (Alexander
Duyck)
- use generic SR-IOV enable for ena, nvme (Alexander Duyck)
- add ACS quirk for Intel 7th & 8th Gen mobile (Alex Williamson)
- add ACS quirk for Intel 300 series (Mika Westerberg)
* pci/virtualization:
PCI/IOV: Allow PF drivers to limit total_VFs to 0
PCI: Add "pci=noats" boot parameter
PCI: Add ACS quirk for Intel 300 series
PCI: Add ACS quirk for Intel 7th & 8th Gen mobile
nvme-pci: Use pci_sriov_configure_simple() to enable VFs
net: ena: Use pci_sriov_configure_simple() to enable VFs
PCI/IOV: Add pci-pf-stub driver for PFs that only enable VFs
PCI/IOV: Add pci_sriov_configure_simple()
