Mmm, I get two modes for each of my ethernet devices:

sm01@stt008:~$ grep -i eth /proc/interrupts
 20:          1          0          0          0   IO-APIC-fasteoi   eth1
1276:     104018     104203     104044     103894   PCI-MSI-edge      eth0

I wonder what's the difference between those two :-?

As per this post:

I'd say if msi-x is enabled it should be present.
