Merge branch 'pci/virtualization' into next

* pci/virtualization:
  ixgbe: Use pcie_flr() instead of duplicating it
  IB/hfi1: Use pcie_flr() instead of duplicating it
  PCI: Call pcie_flr() from reset_chelsio_generic_dev()
  PCI: Call pcie_flr() from reset_intel_82599_sfp_virtfn()
  PCI: Export pcie_flr()
  PCI: Add sysfs sriov_drivers_autoprobe to control VF driver binding
  PCI: Avoid FLR for Intel 82579 NICs
