Kenneth D. Merry be4aa869c1 Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 
14.00.00.01-fbsd.

Their description of the changes is as follows:

1.	Copyright contents has been changed in all respective .c
	and .h files

2.	Support for WRITE12 and READ12 for direct-io (warpdrive only)
	has been added.

3.      Driver has added checks to see if Drive has READ_CAP_16
	support before sending it down to the device.
	If SPC3_SID_PROTECT flag is set in the inquiry data, the
	device supports protection information, and must support
	the 16 byte read capacity command, otherwise continue without
	sending read cap 16. This will optimize driver performance,
	since it will not send READ_CAP_16 to the drive which does
	not have support of READ_CAP_16.

4.      With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not
	use DELAY() which is busy loop implementation.
	It will use <msleep> (Better way to sleep without busy
	loop). Also from the HBA reset code path and some other
	places, DELAY() is replaced with msleep() or "pause()",
	which is based on sleep/wakeup style calls.  Driver use
	msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP
	flags to avoid busy loop which is not required all the
	time.e.a

	a. While driver is getting loaded, driver calls most of the
	   commands with NO_SLEEP.
	b. When Driver is functional and it needs Reinit of HBA,
	   CAN_SLEEP flag is used.

5.	<mpslsi> driver is not Endian safe. It will not work on Big
	Endian machines	like Sparc and PowerPC platforms because it
	assumes it is running on a Little Endian machine.

	Driver code is modified such way that it does not assume CPU
	arch is Little Endian.
	a. All places where Driver interacts from HBA to Host, it
	   converts Little Endian format to CPU format.
	b. All places where Driver interacts from Host to HBA, it
	   converts CPU format to Little Endian.

6.	Findout memory leaks in FreeBSD Driver and resolve those,
	such as memory leak in targ's luns creation/deletion.
	Also added additional checks to see memory allocation
	success/fail.

7.	Add loginfo prints as debug message, i.e. When FW sends any
	loginfo, Driver should print those as debug message.
	This will help for debugging purpose.

8.	There is possibility to get config request timeout. Current
	driver is able to detect config request timetout, but it does
	not do anything on config_request timeout.  Driver should
	call mps_reinit() if any request_poll (which is called as
	part of config_request) is time out.

9.	cdb length check is required for 32 byte CDB. Add correct mpi
	control value for 32 bit CDB as below while submitting SCSI IO
	Request to controller.
	mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT;

10.	Check the actual status of Message unit reset
	(mps_message_unit_reset).Previously FreeBSD Driver just writes
	MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack
	(it just wait for 50 millisecond).  So, Driver now check the
	status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing
	it to the FW.

	Now it also checking for whether doorbell ack uses msleep with
	proper sleep flags, instead of <DELAY>.

11.	Previously CAM does not detect Multi-Lun Devices. In order to
	detect Multi-Lun Devices by CAM the driver needs following change
	set:
	a. There is "max_lun" field which Driver need to set based on
	   hw/fw support. Currently LSI released driver does not set
	   this field.
	b. Default of "max_lun" should not be 0 in OS, but it is
	   currently set to 0 in CAM layer.
	c. Export max_lun capacity to 255

12.	Driver will not reset target info after port enable complete and
	also do Device removal when Device remove from FW.  The detail
	description is as follows
	a. When Driver receive WD PD add events, it will add all
	   information in driver local data structure.
	b. Only for WD, we have below checks after port enable
	   completes, where driver clear off all information retrieved
	   at #1.
	if ((sc->WD_available &&
             (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) ||
             (sc->WD_valid_config && (sc->WD_hide_expose ==
                            MPS_WD_HIDE_IF_VOLUME)) {
		  // clear off target data structure.
	}
	It is mainly not to attach PDs to OS.

	FreeBSD does bus rescan as older Parallel scsi style. So Driver
	needs to handle which Drive is visible to OS.  That is a reason
	we have to clear off targ information for PDs.

	Again, above logic was implemented long time ago. Similar concept
	we have for non-wd also. For that, LSI have introduced different
	logic to hide PDs.

	Eventually, because of above gap, when Phy goes offline, we
	observe below failure. That is what Driver is not doing complete
	removal of device with FW. (which was pointed by Scott)
	Apr  5 02:39:24 Freebsd7 kernel: mpslsi0: mpssas_prepare_remove
	Apr  5 02:39:24 Freebsd7 kernel: mpssas_prepare_remove 497 : invalid handle 0xe

	Now Driver will not reset target info after port enable complete
	and also will do Device removal when Device remove from FW.

13.	Returning "CAM_SEL_TIMEOUT" instead of "CAM_TID_INVALID"
	error code on request to the Target IDs that have no devices
	conected at that moment.  As if "CAM_TID_INVALID" error code
	is returned to the CAM Layaer then it results in a huge chain
	of errors in verbose kernel messages on boot and every
	hot-plug event.
