We see this as a good starting point to build on, we need baseline numbers
for performance, latency, interrupt throughput on real hardware
ASAP to build competency for NFV, which has demanding Dev. Passthrough
requirements. Over time we plan contributing to SMMU and VFIO as well
(we're looking into this now).

FYI NFV is an initiative wireless/fixed network operators are working 
towards - to virtualize Core, likely Radia Access and even Home Network 
equipment, this is a epic undertaking (i.e. Network Function Virtualization). 
So far VMware has taken the lead (mostly x86).

I'll email you offline, I'd like to know more what you've done on this
and see where we can align/leverage the effort.
