Miscellaneous Small Fixes - part 2
- Fix ndlp left in PLOGI state after link up
- Fix cannot rcv unsol ELS frames after running HBA resets for a few minutes
- Fix HBQ buffer_count implemention
- Fix RPI leak
- Fix crash while deleting vports while HBA is reset
- Revert the FCP Fbits offset back to 7
- Fix panic when deleting vports
- Remove unused code in switch statement outside of a case
- Reject PLOGI from invalid PName or NName of 0
- Ignore PLOGI responses from WWPName or WWNName of 0
- Fix debugfs hbqinfo display for ppc
- Added 8G to list of supported speeds for sysfs parameter
- Defer ndlp cleanup to dev-loss timeout handler
- Added support for WRITE_VPARMS mailbox command by applications
