Subject: [PATCH net-next v2 0/8] 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

David Ahern (8):
  rtnetlink: Do not generate notifications for MTU events
  rtnetlink: Do not generate notification for UDP_TUNNEL_PUSH_INFO
  rtnetlink: Do not generate notifications for CHANGEADDR event
  rtnetlink: Do not generate notifications for POST_TYPE_CHANGE event
  rtnetlink: Do not generate notifications for PRECHANGEUPPER event
  rtnetlink: Do not generate notifications for CHANGELOWERSTATE event
  rtnetlink: Do not generate notifications for NETDEV_CHANGEUPPER event
  rtnetlink: Do not generate notifications for
    NETDEV_CHANGE_TX_QUEUE_LEN event
