There are 2 things here. One is to add extended functionality into Linux driver, Another is to have it upstream into kernel world. The first one can be achieved easier, while later one may be difficult. They will have concern why VM can have such privilege (like promisc mode). But I need to check as I know there is some mechanism now to make a VM privileged.
