[SCSI] lpfc: bug fixes
Following the NPIV support, the following changes have been accumulated
in the testing and qualification of the driver:
- Fix affinity of ELS ring to slow/deferred event processing
- Fix Ring attention masks
- Defer dev_loss_tmo timeout handling to worker thread
- Consolidate link down error classification for better error checking
- Remove unused/deprecated nlp_initiator_tmr timer
- Fix for async scan - move adapter init code back into pci_probe_one
context. Fix async scan interfaces.
- Expand validation of ability to create vports
- Extract VPI resource cnt from firmware
- Tuning of Login/Reject policies to better deal with overwhelmned targets
- Misc ELS and discovery fixes
- Export the npiv_enable attribute to sysfs
- Mailbox handling fix
- Add debugfs support
- A few other small misc fixes:
- wrong return values, double-frees, bad locking
- Added adapter failure heartbeat
