    bonding: Prevent duplicate userspace notification · 7a7e96e0
    Vlad Yasevich authored
    Whenever a user changes bonding options, a NETDEV_CHANGEINFODATA
    notificatin is generated which results in a rtnelink message to
    be sent.  While runnig 'ip monitor', we can actually see 2 messages,
    one a result of the event, and the other a result of state change
    that is generated bo netdev_state_change().  However, this is not
    always the case. If bonding changes were done via sysfs or ifenslave
    (old ioctl interface), then only 1 message is seen.
    This patch removes duplicate messages in the case of using netlink
    to configure bonding.  It introduceds a separte function that
    triggers a netdev event and uses that function in the syfs and ioctl
    This was discovered while auditing all the different envents and
    continues the effort of cleaning up duplicated netlink messages.
