Yes, it is enabled.

The Linux driver also sais TQ is enabled on the SAS drives. As I said,
the adapter doesn´t like that for now. Maybe some queue size
parameters have to be tuned.
Regarding RAID settings, in order to change these
MPI_FUNCTION_RAID_ACTION has to be called. There also has to be a
Request/Reply structure which isn´t defined in mpt_mpilib.h yet. I
started designing these, inspired by the OpenBSD driver:
==========================================
typedef struct _MPI_MSG_RAID_ACTION_REQUEST {
U8 Action;
U8 Reserved1;
U8 ChainOffset;

U8 VolId;
U8 VolBus;

U8 MessageFlags;
U32 MsgContext;
U32 Reserved2;
U32 DataWord;
U32 DataSge;
} MPI_MSG_RAID_ACTION_REQUEST;

====================
This is also a prerequisite for bio(4) support.
