Merge branch 'rtnetlink-cleanup-user-notifications'
David Ahern says: ==================== rtnetlink: Cleanup user notifications for netdev events Vlad's recent patch to add the event type to rtnetlink notifications points out a number of redundant or unnecessary notifications sent to userspace for events that are essentially internal to the kernel. Trim the list to put a dent in the notification storm. v2 - rebased to top of net-next with IFLA_EVENT patch reverted - dropped removal NETDEV_CHANGEINFODATA since it is intentionally only to send a message to userspace - dropped NOTIFY_PEERS since Vlad's says it is needed for macvlans - add patches to remove NETDEV_CHANGEUPPER and NETDEV_CHANGE_TX_QUEUE_LEN from the event list ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
