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
====================
