From: Swen Schillig <swen@xxxxxxxxxxxx> If an exchange config is executed while the local link is down, the request succeeds but the returned data is incomplete. Proceeding with the adapter activation is leading to an unpredictable behaviour (e.g. kernel panic) caused by invalid values. In such a scenario the recommended ERP is to retry the action and wait for a link up event. If the issue persists the activation has to fail.
