Subject: [PATCH] add HAVE_UNREGISTER_NETDEV_QUEUE define for out-of-tree modules

Hello,

I have an out of tree network driver (GPL'd) that would like to make use of 
the unregister_netdevice_queue interface for bulk unregister of devices.  
Add a #define HAVE_UNREGISTER_NETDEV_QUEUE to allow the source to detect 
that the kernel supports this.
