    IB/qib: fix IPoIB device stop deadlock
    
    We create our own workqueue mainly because we want to be
    able to flush it when devices are being removed.  We can't
    use schedule_work()/flush_scheduled_work() because both
    unregister_netdev() and linkwatch_event take the rtnl lock,
    so flush_scheduled_work() can deadlock during device removal.

    IB/qib: serdes changes for QME7342 serdes
    
    Because we now have different values of H1 all over, I redid the h1_vals
    code that we weren't really using, changed it to a single h1_val,
    and initialized for the board types that need different values.
