scsi: lpfc: SLI path split: Refactor fast and slow paths to native SLI4
[ Upstream commit 1b64aa9eae28ac598a03ed3d62a63ac5e5b295fc ]
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
