   This patch changes the Ethernet bridge back to the original way
   without having a destructor function.  This is done so the route
   cache side effect code doesn't hold onto a reference to the device.

If destructors are racy and do not work, we don't fix this
by removing destructors from netdevice drivers.

I do not accept this patch.  We must fix the core problem.

And your patch even creates a new problem.  Remember how Alexey
mentioned that that spinning/sleeping loop in unregister_netdevice()
is deadlock prone and basically illegal itself.
