Subject: RE: configure VF parameters from PF domain


There is no such tool yet.  Proposals for such a tool are welcome.  There are some discussions going on between myself and a few other engineers as to how to proceed but nothing beyond that yet.

I agree completely that such a tool is necessary for SR-IOV networking to move from expermimental to something actually useful in real world applications.
