Browse Source 
- Fix vport ndlp ref counting errors
- Fix use after free of ndlp structure
- Use the correct flag to check for LOADING setting.
- Fix driver unload bugs (related to shost references) after link down or rscn
- Fix up HBQ initialization
- Fix port_list locking around driver unload.
- Fix references to hostdata as a phba
- Fix GFFID type offset to work correctly with big endian structure.
- Only call pci_disable_msi if the pci_enable_msi succeeded
- Fix vport_delete wait/fail if in discovery
- Put a reference on the nameservers ndlp when performing CT traffic.
- Remove unbalanced hba unlock.
- Fix up HBQ processing
- Fix lpfc debugfs discovery trace output for ELS rsp cmpl
- Send ADISC when rpi is 0
- Stop FDISC retrying forever
- Unable to retrieve correct config parameter for vport
- Fix sli_validate_fcp_iocb, sli_sum_iocb, sli_abort_iocb to be vport-aware.
- Fix index-out-of-range error in iocb. Spotted by Coverity.
