Hi Markus,

Thanks for the patch!
I thought that it might only need the support ‘switch’ flipped on, but wasn’t sure.
It seems to work, though I get the following message when testing using `testpmd`:
	EAL: Error enabling MSI-X interrupts for fd 26
I’ve also seen a couple of lost packets, which I wonder if are due to the above.
So I guess it’s missing /something/ to be entirely supported, but with this it does work (at least partially).

Thanks!
Omri
