adding/removing the devices from FW
Driver will update the OS devices after adding and deleting the device
from FW. When driver receive add or delete AEN from FW, driver will
send the DCMD cmd to get the System PD list from FW. Then driver will
check if this device already in the OS: If add event and OS don't have
the device (but it is in the list), driver add the device to OS,
otherwise driver will not add. If remove event, driver will check the
list, if is not in the list, but OS have the device, driver will
remove the device.

(1) target resets are sending link change rate events with no link rate
change -> thus said the driver was modified so when there is no link rate
change, we don't need to call mpt2sas_transport_update_links nor
_scsih_ublock_io_device.
(2) There were changes made in _scsih_sas_topology_change_event_debug to
change the debug strings so they are more clear. Also the link rate change
information was added to display the new and previous link rate.
for the MPI2_EVENT_SAS_TOPOLOGY_CHANGE_LIST event when the ExpStatus is
set to zero, display "responding" instead of "unknown status".

shutdown
(1) Added new function _scsih_ir_shutdown. This function will issue the
MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED request via
MPI2_FUNCTION_RAID_ACTION. The function will wait 10 seconds for reply
message frame, then print out the ioc status and loginfo. This function is
only called when there are raid volumes present.
(2) Add shutdown callback in the struct pci_driver object scsih_driver. This
will be called only when the system is shutting down. From this function, we
will call _scsih_ir_shutdown mentioned above.
(3) Add support in _scsih_remove to call _scsih_ir_shutdown. The function
_scsih_remove will be called when the driver is unloaded (and system is
still running).
scsih internal command contex is added to send internal message frames
from mpt2sas_scsih.c.

When receiving the MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET event,
the driver will set the tm_busy flag in the sdev private host data, When
tm_busy flag is set, the driver will return SCSI_MLQUEUE_DEVICE_BUSY,
effectly freezing the IO to the device. The tm_busy flag is cleared with the
MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET event.

(1) EEDP(End to End data protection) was not working. This was due to not
setting EEDP BlockSize and Flags to little endian format in the message
frame.
(2) Some expander sysfs attributes were not getting set properly. The sas
format was not getting set due to endian issues with sas_format field in the
struct rep_manu_reply. Since sas_format was not set properly, the
component_vendor_id, component_revision_id, and component_id were not set.
(3) In _transport_smp_handler: we don't need to convert the smid from little
endian to cpu prior to calling mpt2sas_base_free_smid, because its allready
in cpu format. (4) Some loginfos and ioc status were not xonverted from
little endian to cpu.

loss,SCSI_MLQUEUE_DEVICE_BUSY if device is busy
1 Its observed that the OS was sending request to the driver after it had been
put into blocking state, so the driver was modified to return
SCSI_MLQUEUE_DEVICE_BUSY.
2. Driver will return DID_TRANSPORT_DISRUPTED when sdev is haivng nexus loss.
This occurrs when sdev is blocked, between the
MPI2_EVENT_SAS_TOPO_RC_DELAY_NOT_RESPONDING and
MPI2_EVENT_SAS_TOPO_RC_TARG_NOT_RESPONDING events.

READY state
The driver needs to retrieve the ioc facts prior to putting the controller
into READY state. The current design is calling ioc facts after putting the
controller into READY state, which means the driver is sending a diag reset
instead of message unit reset becuase the capability information is not yet
available.

Added command line option diag_buffer_enable. When the command line option is
set, the driver will automatically post diag buffers at driver load time.
The command line option diag_buffer_enable is bitwise, so it's possible to
enable both and/or snapshot + trace buffers. For trace, the driver will
allocate 1MB buffer, whereas for snapshot its 2MB. The purpose for this is
so the enduser doesn't have to manually use an application to setup diag
buffers for debugging firmware related issues.
Here is some examples
trace:
# insmod mpt2sas.ko diag_buffer_enable=1
snapshot:
# insmod mpt2sas.ko diag_buffer_enable=2
both trace and snapshot:
# insmod mpt2sas.ko diag_buffer_enable=3

Added command line option and shost sysfs attribute called
mpt2sas_fwfault_debug. When enduser writes a "1" to this parameter, this
will enable support in the driver for debugging firmware timeout related
issues. This handling was added in three areas (a) scsi error handling
callback called task_abort, (b) IOCTL interface, and (c) other timeouts that
result in diag resets, such as manufacturing config pages. When this
support is enabled, the driver will provide dump_stack to console, halt
controller firmware, and panic driver. The end user probably would want to
setup serial console redirection so the dump stack can be seen.
Here are the three methods for enable this support:
(a) # insmod mpt2sas.ko mpt2sas_fwfault_debug=1
(b) # echo 1 > /sys/module/mpt2sas/parameters/mpt2sas_fwfault_debug
(c) # echo 1 > /sys/class/scsi_host/host#/fwfault_debug (where # is
the host number)

add.
This handles the case where driver receives a expander removal event while
it is in the middle of processing an expander add event. The existing
implementation will stop processing futher device adds when a expander
delete arrives on top of add expander add. Due to a sanity check in the
driver, the devices there were not added, were never handshaked to firmware
with the device removal handshake protocal. Since the driver didnt' do the
handshake, the controller never provide further add events. To fix this
issue, the sanity check was removed so the driver will always do the device
removal handshake protocal.

The device driver was not handling updating device handles in all cases
across diag resets. To fix this issue, the driver is converted to using sas
address instead of handle as a lookup reference to the parent expander or
sas_host. Also, for both expanders and sas host, the phy handle will be one
unique handle. In the sas host case, the phy handle can be different for
every phy, so the change is to set the handle to the handle of the first
phy; every phy will be one single sas address(phy 0) instead of a different
sas address for every phy(previous implementation). So making one consistent
sas address for all the direct attachedports to the sas host, will make it
better user experience when using udev /dev/disk/by-path dev nodes

while dropping the wild guess for AMD based 6735 having the same

series/family, thus is not probable for 673x).
