[PATCH 5.15 703/779] scsi: lpfc: SLI path split: Refactor SCSI paths

From: Greg Kroah-Hartman
Date: Mon Aug 15 2022 - 15:55:06 EST

From: James Smart <jsmart2021@xxxxxxxxx>

[ Upstream commit 3512ac0942938d6977e7999ee69765d948d2faf1 ]

This patch refactors the SCSI paths to use SLI-4 as the primary interface.

- Conversion away from using SLI-3 iocb structures to set/access fields in
common routines. Use the new generic get/set routines that were added.
This move changes code from indirect structure references to using local
variables with the generic routines.

- Refactor routines when setting non-generic fields, to have both SLI3 and
SLI4 specific sections. This replaces the set-as-SLI3 then translate to
SLI4 behavior of the past.
