Christmas in summer on the northern hemisphere :-)

Unfortunately the only machine I have available for tests won't do 
SR-IOV as far as I remember, since this feature is disabled for E3-Xeons.

I can't remember all the details, but I gave up with SR-IOV on any Intel 
single-socket platform since E5-1600 v3/5 never showed up :-(
Although FreeBSD wasn't involved, I guess the basic requirements are the 
same and I don't have a chance to use SR-IOV on E3-Xeon (v2, C203 BearTooth)

Shall I falsify with mps(4)?  I think this supports VFs and I have one 
in spare.

I'm very sorry that I won't be able to test anything – but if I'm the 
only igb-VF consumer, not capable of using it currently at all, Ryan 
might be right with the waste of time...
