ipv6: export function to send route updates
Add fib6_rt_update to send RTM_NEWROUTE with NLM_F_REPLACE set. This helper will be used by the nexthop code to notify userspace of routes that are impacted when a nexthop config is updated via replace. This notification is needed for legacy apps that do not understand the new nexthop object. Apps that are nexthop aware can use the RTA_NH_ID attribute in the route notification to just ignore it. In the future this should be wrapped in a sysctl to allow OS'es that are fully updated to avoid the notificaton storm. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
