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 cases. This was discovered while auditing all the different envents and continues the effort of cleaning up duplicated netlink messages.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
