[SCSI] lpfc 8.2.2 : Miscellaneous management and logging mods
- Remove the "management_version" sysfs parameter (was unused) - Add HBQ information to lpfc debugfs - Change lpfc_npiv_enable name back to lpfc_enable_npiv (internal stds) - Remove "issue_lip" attribute from the vports transport template Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
