IMO, it doesn't sound anymore complicated than making virtio support the
concepts already provided by vbus/venet-tap driver. Isn't there already
precedent for alternative approaches co-existing and having the users
decide which is the most appropriate for their use case? Switching
drivers in order to improve latency for a certain class of applications
would seem like something latency sensitive users would be more than
willing to do. I'd like to point out 2 things. Greg has offered help
in moving virtio into the vbus infrastructure. The vbus infrastructure
is a large part of what is being proposed here.
