commit 4b793acdca0050739b99ace6a8b9e7f717f57c6b upstream.
When HSR interface is sending a frame, it finds a node with the destination ethernet address from the list. If there is no node, it calls WARN_ONCE(). But, using WARN_ONCE() for this situation is a little bit overdoing. So, in this patch, the netdev_err() is used instead.
