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

Please Vladimir, could you reply to Stephen?
I think he is suggesting a better fix in the igc driver.
