The patch refactors the general ELS handling paths to migrate to SLI-4 structures or common element abstractions. The fabric login paths are revised as part of this patch:
- New generic lpfc_sli_prep_els_req_rsp jump table routine
- Introduce ls_rjt_error_be and ulp_bde64_le unions to correct legacy endianness assignments
- 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.
- Clean up poor indentation on some of the ELS paths
