scsi: lpfc: SLI path split: Refactor fast and slow paths to native SLI4
[ Upstream commit 1b64aa9e ] Convert the SLI4 fast and slow paths to use native SLI4 wqe constructs instead of iocb SLI3-isms. Includes the following: - Create simple get_xxx and set_xxx routines to wrapper access to common elements in both SLI3 and SLI4 commands - allowing calling routines to avoid sli-rev-specific structures to access the elements. - using the wqe in the job structure as the primary element - use defines from SLI-4, not SLI-3 - Removal of iocb to wqe conversion from fast and slow path - Add below routines to handle fast path lpfc_prep_embed_io - prepares the wqe for fast path lpfc_wqe_bpl2sgl - manages bpl to sgl conversion lpfc_sli_wqe2iocb - converts a WQE to IOCB for SLI-3 path - Add lpfc_sli3_iocb2wcqecmpl in completion path to convert an SLI-3 iocb completion to wcqe completion - Refactor some of the code that works on both revs for clarity Link: https://lore.kernel.org/r/20220225022308.16486-3-jsmart2021@gmail.com Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.
