I merged the tunable only a few days ago. Glen, do you think this warrants an errata notice? I think it'd be necessary to disable mfi(4) using something like hints.mfi.0.disabled="1" in order to use mrsas(4) on 9.3. That's a bit more heavy-handed than the mrsas_enable tunable, since it prevents mfi(4) from attaching even if mrsas(4) doesn't support the controller in question.
