- * Applicable in Initiator, Target and NIC modes.
- * A link state async event is seen by all device drivers as soon they
- * create an MCC ring. Thereafter, anytime the link status changes the
- * drivers will receive a link state async event. Notifications continue to
- * be sent until a driver destroys its MCC ring. A link down event is
- * reported when either port loses link. A link up event is reported
- * when either port regains link. When BE's failover mechanism is enabled, a
- * link down on the active port causes traffic to be diverted to the standby
- * port by the BE's ARM firmware (assuming the standby port has link). In
- * this case, the standy port assumes the active status. Note: when link is
- * restored on the failed port, traffic continues on the currently active
- * port. The ARM firmware does not attempt to 'fail back' traffic to
- * the restored port.
