Comment 1 for bug 1640969

However, at the moment networking-calico works with >= Kilo (as discussed in https://bugs.launchpad.net/networking-calico/+bug/1640967), but the required AFTER_INIT/AFTER_CREATE notification was only added for Liberty. So, to adopt the latter approach, we'd either need to rethink our Kilo support, or to retain the existing code as well as a new notification-based approach, but only use the existing code with Kilo.
