[SCSI] lpfc 8.3.2 : Reorganization for SLI4
Preps the organization of the driver so that the bottom half, which interacts with the hardware, can share common code sequences for attachment, detachment, initialization, teardown, etc with new hardware. For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.
