Commit Message

Xin Long Oct. 24, 2017, 5:54 a.m. UTC 
Since commit 42e52bf9e3ae ("net: add netnotifier event for upper device
change"), netdev_master_upper_dev_link has generated NETDEV_CHANGEUPPER
event which would send a notification to userspace in rtnetlink_event.

There's no need to call rtmsg_ifinfo to send the notification any more.
So this patch is to remove it from bond_master_upper_dev_link as well
as bond_upper_dev_unlink to avoid the redundant notifications.
