    if_tap/if_tun - Remove pre-created devices
    * The pre-created devices cause bitmap confusion between the
      if autoclone bitmap tracking in netif and the bitmap tracking
      in the device drivers.
      Just remove the pre-created devices entirely.  Users must manually
      create the appropriate tap or tun interface, or use the auto-cloning
      device (/dev/tap and /dev/tun).
    * Fixes panics and auto clone create errors related to this confusion.
