[dpdk-dev] [PATCH v6 3/5] igb_uio: fix MSI-X IRQ assignment with new IRQ function

[Markus Theil]

The patch which introduced the usage of pci_alloc_irq_vectors
came after the patch which switched to non-threaded ISR (f0d1896fa1),
but did not use non-threaded ISR, if pci_alloc_irq_vectors
is used.

Fixes: 99bb58f3adc7 ("igb_uio: switch to new irq function for
MSI-X")
