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.
