I think the biggest hurdle is that for igb, the pf and vf should be split. That
was being considered at the same time as the ixgbe/ixgbevf split, but there was
little interest at the time.

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...
