Hi Flavio,
Thank you for reviewing the document!

For some reason I thought we still need eventfd_link to notify the guests
when new packets arrive. Indeed we don't need this anymore, I updated the wiki 
page.

Regarding QEMU, can you please point me to the missing setup steps?
(I think I already took care of them, anyway I want to be sure)


Thanks,
Marcel
