[PATCH 8/9] lpfc: Beef up stat counters for debug

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If log verbose in not turned on, its hard to tell when
certain error paths get hit. Add stats counters and
corresponding logic to debugfs/sysfs to aid understanding
what paths were traversed.
