Description (partial)

Symptom:
Only FEX hifs that are up show up in "sh fex <id> detail".

Conditions:
Issue is related to ISSU non disruptive.  In this particular case, ISSU failed with the line card upgrade sequence failure and after that another ISSU non disruptive was performed on the switch. Second ISSU was performed on the inconsistent state that resulted in this error. After the first ISSU failure, the customer should have reloaded the switch as the switch state was not consistent and might have resulted in the topology changes as well.
