Many thanks. Now if only IPv4 would be fixed in similar fashion as well.

Also, this reminds me related issue - "ADDRCONF(NETDEV_UP): <ifname>: link
is not ready" and "ADDRCONF(NETDEV_CHANGE): <ifname>: link becomes ready"
messages. While it may look informational, it's extremely annoying in
systems with hundreds and even thousands vlan interfaces.
