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) ?
