Is there any way to print the addresses the notifier is calling
to try and release net device references? I see:

net/core/dev/c::netdev_wait_allrefs():

        while (atomic_read(&dev->refcnt) != 0) {
                if (time_after(jiffies, rebroadcast_time + 1 * HZ)) {
                        rtnl_lock();

                        /* Rebroadcast unregister notification */
                        raw_notifier_call_chain(&netdev_chain,
                                            NETDEV_UNREGISTER, dev);

but don't see any way to print the functions that get called.
