net: hsr: Don't log netdev_err message on unknown prp dst node
If no frames has been exchanged with a node for HSR_NODE_FORGET_TIME, the node will be deleted from the node_db list. If a frame is sent to the node after it is deleted, a netdev_err message for each slave interface is produced. This should not happen with dan nodes because of supervision frames, but can happen often with san nodes, which clutters the kernel log. Since the hsr protocol does not support sans, this is only relevant for the prp protocol. Signed-off-by: Kristian Overskeid <koverskeid@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
