Description (partial)

Symptom:
Credit loss recovery occurred on a interface which causes the MDS to transmit a Link Reset(LR). If the Link Reset does not complete by receiving a Link Reset Response(LRR) within 100ms the MDS should timeout the LR and fail the interface. If that 100ms timeout does not occur the interface will be stuck transmitting LRs. This is a request to error disable the interface if the normal 100ms LR timeout does not occur.

Conditions:
Unknown.
