This Kconfig option is only used for legacy mpt2sas/mpt3sas interoperability. Once this config is set, out of box driver mpt2sas and mpt3sas can reconginize difference between merged and legacy inbox driver. Used only to interface gracefully between old mpt2sas/mpt3sas and merged mpt3sas driver. Allways set for merged mpt3sas driver.
