SILI-3132 driver progress report.

[Matthew Dillon]

    The SILI driver passed its basic port multiplier tests with no
    corruption.  I did a copy chain on a 3.2TB stripe across 4 disks
    over a period of a day and a sweep of the HAMMER filesystem showed
    no corruption afterwords.

    I am continuing to do more extensive tests.  I haven't tested with
    significant popping and insertion of drives yet (idle drives in the
    same PM containing the drives under test).  That is planned.

    I'm comfortable with both the SILI and the AHCI driver now.
