Hmm, we need to fill this in before you start using it for virt.
After all, it's very difficult for the guest to know whether the
output device on the host is going to be able to do UFO or not.
Yep, no point telling the guest we support UFO if we don't!
This path is taken only when the packet needs to go out a device that
doesn't support UFO.
Until the software UFO is supported, I thought it may be useful to
provide a way to enable
UFO inter-guest, between host to guest and to an external host via an
outgoing device that supports UFO.
Thanks
