Hmm, might this break ipoib? It currently does:

void ipoib_event(struct ib_event_handler *handler,
                 struct ib_event *record)
{
        struct ipoib_dev_priv *priv =
                container_of(handler, struct ipoib_dev_priv, event_handler);

        if (record->event == IB_EVENT_PORT_ERR    ||
            record->event == IB_EVENT_PKEY_CHANGE ||
            record->event == IB_EVENT_PORT_ACTIVE ||
            record->event == IB_EVENT_LID_CHANGE  ||
            record->event == IB_EVENT_SM_CHANGE) {
                ipoib_dbg(priv, "Port state change event\n");
                queue_work(ipoib_workqueue, &priv->flush_task);
        }
}

Don't we need to add IB_EVENT_CLIENT_REREGISTER too?
