Correction. I checked and it appears that there is a bug on MSI-X on 
currently released firmware. The bug will be fixed on FW 3.3.0. The bug is 
about endianess, so it's theoretically possible to workaround it, or just 
wait for the release. I'd wait for the release and get the driver developed 
much easily. Roland, what do you say?
