I'm fine with the basic idea, but the implementation needs work and
this will be deferred to 3.16 in any event.

We really need to specify the name allocation type at alloc_netdev()
time, I know that's more work but that's the only way you can be sure
you caught all such cases.

I know you missed the ISDN layer, where the name can come from the
user via an ioctl().  I'm sure there were several more.

You can even do something like make alloc_netdev_enumerated()
be a shorthand for alloc_netdev(size, name, NET_NAME_ENUM, ...)

Thanks.
