parentipv6: Only Replay routes of interest to new listeners (diff)
ipv6: Handle route deletion notification
For the purpose of route offload, when a single route is deleted, it is only of interest if it is the first route in the node or if it is sibling to such a route. In the first case, distinguish between several possibilities: 1. Route is the last route in the node. Emit a delete notification 2. Route is followed by a non-multipath route. Emit a replace notification for the non-multipath route. 3. Route is followed by a multipath route. Emit a replace notification for the multipath route. In the second case, only emit a delete notification to ensure the route is no longer used as a valid nexthop.
