 Once you download the drivers, you'll find it uses its own stack.
It appears to not use the libata core libs but the scsi core and its own MPT
stack.

 From the driver modules 
SATA errors:
                "SATA Non-NCQ RW Error Bit Set",                /* 06h */
                "SATA Read Log Receive Data Error",             /* 07h */
                "SATA NCQ Fail All Commands After Error",       /* 08h */
                "SATA Error in Receive Set Device Bit FIS",     /* 09h */
 
MODULE_PARM_DESC(mpt_sas_hot_plug_enable, " Enable SAS Hot Plug Support: enable= 1 (default=1)");

It supports some form of NCQ and hotplug support is enabled by default.

Anymore than this will require calling tech support and asking, or actually
finding someone using the same setup.
