    ipv6: export function to send route updates · 19a3b7ee
    David Ahern authored
    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.
