Description
Upon detection of a "link down" event, the "fatal" flag is set on the corresponding NI marking it as ineligible for selection on tx, but at the same time the NIs health score remains unchanged. This means that as soon as the link comes back up, the "fatal" flag is removed making the NI available for selection with the same health score as before the "link down" event.
It is proposed to slow down the reintroduction the NI into the tx selection in this case by degrading its health score to 0 on a "fatal" event. This would force NI to go through local recovery before its score is restored to maximum level. This can help the system stay more resilient when dealing with "link flapping".
