Description (partial)


when induce SPI mcast high priority ack barrier timeout twice in one minute, s/w doesn't take link off line permanently


The HW team's recommendation is to permanently shut such repeat offenders. But the driver does not perm-shut the links
and keeps bringing them up.

Whan a fabric hardware on a particular plane goes bad and keeps affecting the barrier/data flow in such a way that
the links from that plane to fabricq ASICs timeout for barriers, such links must be perm-shut to prevent the problem from
affecting other planes.
