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
