We do need it because of the problems with vdev_netvsc.
The issue is that vdev_netvsc tries to setup failsafe on all netvsc
devices it sees, and it determines which ones are used by OS based on
somewhat fragile OS probes with netlink.

I would recommend getting rid of vdev_netvsc, or make the the auto
scanning there something that has to be forced by devargs.
But that really is up to the netvsc maintainers.
