The PSILSS provides MMRs that show the current link status of all the PSIL endpoints. It also tracks and provides status MMRs of any links that went down, from being active and running to a down state when the PSILSS is not in reset. This detection can generate an event so that software can remedy the situation. The hardware does not cleanup the traffic, so software must take care to idle any traffic before an endpoint is reset, which causes the link to go down, as well as to cleanup any connections after an endpoint has gone down. Software must guarantee the endpoint link is up again before setting up new connections.
