NAME
       unregister_netdevice_queue - remove device from the kernel

       void unregister_netdevice_queue(struct net_device * dev, struct list_head * head);

ARGUMENTS
       dev
	   device

DESCRIPTION
       This function shuts down a device interface and removes it from the kernel tables. If head not NULL, device is queued to be unregistered
