OK, when I said the PV stack, I meant the portion of the PV stack which assumes Ethernet link layer, ofcourse... If someone uses routing they don't need this driver. Again, since the app only uses IP, which is well defined, etc. the work done by the eipoib driver, didn't seem as hackish messing, so I'm again with that WW (Why/What) question from 5m ago. Or.
