The problem is that netdev_all_lower_get_next_rcu() never advances the
iterator, thereby causing the loop over the lower adjacency list to run
forever.

Fix this by advancing the iterator and avoid the infinite loop.

Applied.

Below the patch I noted "Please consider queueing this for 4.8.y", but
you didn't reply and I don't see it here:
https://patchwork.ozlabs.org/bundle/davem/stable/?state=*

So I'm not sure if this was rejected or you just missed my note.

Thanks
