Merge branch 'msix'
Alexander Gordeev says:
====================
net: Use pci_enable_msix_range() instead of pci_enable_msix()
As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.
