It turned out that the hw.mfi.mrsas_enable tunable hadn't been merged to
stable/10, so setting it had no effect. I fixed that in r270732, so the
r270981 image that you downloaded has it.

I've just added mrsas(4) to the kernel. In a few days that change will
be merged to stable/10, at which point you won't need to manually load
mrsas.ko anymore - setting the tunable will be sufficient.

Thanks,
