You also need to backport mfiutil too.

I have a patch set for 8.3 which include latest mfi driver, mfiutil and
a large set of mfi driver fixes, even head has some rather serious issues
although mainly around error handling on tbolt cards.

We're running this in production so believe its a good stable set.

If you would like the patch set just let me know.

    Regards
    Steve
