Here's the thread: https://www.spinics.net/lists/netdev/msg429154.html The comment is that def12888c161 is adding a uapi that leads to way too many notifications (e.g., on a setlink). It would be more efficient (read less notifications) to have do_setlink emit a single message with the IFLA_EVENT (or something else appropriately named) that indicates what attributes changed. Right now, a change MTU leads to 3 notifications causing unnecessary churn in userspace to track what the state of the link is.
