    [SCSI] mptfusion: Added new less expensive RESET (Message Unit Reset) · d0f698c4
    Kashyap, Desai authored
    Message Unit Reset - instructs the IOC to reset the Reply Post and
    Free FIFO's. All the Message Frames on Reply Free FIFO are
    discarded. All posted buffers are freed, and event notification is
    turned off.  IOC doesnt reply to any outstanding request. This will
    transfer IOC to READY state.  Message unit ready is less expensive
    operations than Hard Reset.  soft reset will not force Firmware to
    reload again, it only do clean up of Message units.
    
    mpt_Soft_Hard_ResetHandler will first try for Soft Reset,if
    it fails then go for big hammer reset which is Hard Reset.
