[PATCH] eal/interrupts: Allow UIO interrupts when using igb_uio

[Vladimir Ratnikov]

Sorry for a long reply, sure.

Stephen,
am I right that the most concern is about a place where interrupt
capabilities check appears for non MSI-X support?
What if having dedicated rte_intr_cap_single analog when there's no support
for MSI-X and just do the same(check capability, allocate interrupt vector
etc) ?


Regards,
-Vladimir
