   If this is true, I think you can use the module reference count only,
   and your code will be faster, too.  I can prepare the patch for you
   later tonight, to see how it looks.
   
And where do we get the counter from when dev->owner is NULL
(ie. non-modular)?  We need the reference counting regardless of
whether the device is implemented statically in the kernel or modular.

But Alexey said you can only call unregister_netdev from module
unload, ie. if not a module, it can't be unloaded, hence no refcount
needed.  I wrote the above paragraph because I'm not sure if I
understood Alexey correctly?

There are several flavors of pseudo-network devices like bridging and VLAN that
dynamically create/destroy netdev's even when they are not modules.
