Note that this option only affects the creation of VLAN interfaces
without specifying a name.  With netlink you can actually pass the name
for the to-be-created interface in the netlink message.  iproute2 allows

  ip link add link eth0 name spam123 type vlan id 456

I do believe that the ioctl/vlanconfig stuff, if not deprecated, is at
least outdated.  Not fully sure though.
