Re: Silicon Image Sil 3112 SATARaid Controller

    The Silicon Image Sil 3112 should be trivially supportable under
    4.x.  Actually, any of the Sil 3xxx controllers should be trivially
    supportable.

    This patch is for the 3512 and the 3114, and its based on DragonFly,
    so it won't patch cleanly into 4.x, but it's so simple that you should
    be able to adapt it to 4.x for the 3112 by entering the correct PCI IDs
    (from pciconf -l).

    This is admittedly a hack, but it seems to work well with my Sil 3512
    even though it does not report the correct speed or type (but still
    operates at the correct speed).

    (There's also an unrelated rman fix in there which may or may not already
    be fixed in 4.x).
