Roland, We encountered a problem that when a machine didn't support the required number of vectors (nvec), instead of trying to get 2 vectors like in the previous version, it didn't use MSI-X at all - causing a major performance degradation. Maybe in a case of failure we should try lowering the number of vectors to 2 (like in the previous version) or the return value of pci_enable_msix and goto no_msi only in case of a second failure.
