Kernel Options: To use MSI-X or not?

[Justin Piszcz]

Hello,

I was curious whether its best to use MSI-X when the driver supports it or 
not?

Example, 3ware cards/Intel Audio Drivers you can use MSI-X instead of 
having several devices use/share an interrupt.

What are the pros/cons to using MSI-X vs. having devices share an IRQ?

Justin.
