netlink: Add field to skip in-kernel notifications
The struct includes a 'skip_notify' flag that indicates if netlink notifications to user space should be suppressed. As explained in commit 3b1137fe7482 ("net: ipv6: Change notifications for multipath add to RTA_MULTIPATH"), this is useful to suppress per-nexthop RTM_NEWROUTE notifications when an IPv6 multipath route is added / deleted. Instead, one notification is sent for the entire multipath route. This concept is also useful for in-kernel notifications. Sending one in-kernel notification for the addition / deletion of an IPv6 multipath route - instead of one per-nexthop - provides a significant increase in the insertion / deletion rate to underlying devices. Add a 'skip_notify_kernel' flag to suppress in-kernel notifications.
