Exactly.  Until our friends at VMware get this basic fact it's useless
to continue arguing.

Pankaj and Dmitry: you're fine to waste your time on this, but it's not
going to go anywhere until you address that fundamental problem.  The
first thing you need to fix in your archicture is to integrate the VF
function code into the kernel tree, and we can work from there.

Please post patches doing this if you want to resume the discussion.
