We have a push model, and state transition notifications are already
implemented.

On the contrary:
static void send_subscription(struct node *node)
{
struct subscribe_events_np sen;
memset(&sen, 0, sizeof(sen));
sen.duration = PMC_SUBSCRIBE_DURATION;
sen.bitmask[0] = 1 << NOTIFY_PORT_STATE;
pmc_send_set_action(node->pmc, TLV_SUBSCRIBE_EVENTS_NP, &sen,
sizeof(sen));
}
Currently, PORT_STATE is the only implemented notification, but the
infrastructure for adding more is in place, just waiting for patches!
Thanks,
