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... -harry
