I had been doing some ifnet work that I'm now abandoning because the review process for this area is simply not worth it: D22691[0]. I'd quite like to see someone else pick it up and finish out, though... I've been running with some success an earlier version of this that coordinates if_vmove() and vnet shutdown's evacuation of ifnets with if_detach() to render some of the common epair/vnet races harmless. Feel free to tag me for reviewing if you want to pick it up. Thanks, Kyle Evans [0] https://reviews.freebsd.org/D22691
