scsi: lpfc: SLI path split: Refactor CT paths
This patch refactors the CT paths to use SLI-4 as the primary interface.
- Introduce generic lpfc_sli_prep_gen_req jump table routine
- Introduce generic lpfc_sli_prep_xmit_seq64 jump table routine
- Rename lpfcdiag_loop_post_rxbufs to lpfcdiag_sli3_loop_post_rxbufs to
indicate that it is an SLI3 only path
- Create new prep_wqe routine for unsolicited ELS rsp WQEs.
- 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.
