This patch refactors the BSG paths to use SLI-4 as the primary interface.
Changes include:
- 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
both sli3 and sli4 specific sections. This replaces the set-as-sli3
then translate to sli4 behavior of the past.
