+2 Current Version : 00.00.04.31-rc1
+3 Older Version : 00.00.04.17.1-rc1
+
+1. Add the Online Controller Reset (OCR) to the Driver.
+ OCR is the new feature for megaraid_sas driver which
+ will allow the fw to do the chip reset which will not
+ affact the OS behavious.
+
+ To add the OCR support, driver need to do:
+ a). reset the controller chips -- Xscale and Gen2 which
+ will change the function calls and add the reset function
+ related to this two chips.
+
+ b). during the reset, driver will store the pending cmds
+ which not returned by FW to driver's pending queue. Driver
+ will re-issue those pending cmds again to FW after the OCR
+ finished.
+
+ c). In driver's timeout routine, driver will report to
+ OS as reset. Also driver's queue routine will block the
+ cmds until the OCR finished.
+
+ d). in Driver's ISR routine, if driver get the FW state as
+ state change, FW in Failure status and FW support online controller
+ reset (OCR), driver will start to do the controller reset.
+
+ e). In driver's IOCTL routine, the application cmds will wait for the
+ OCR to finish, then issue the cmds to FW.
+
+ f). Before driver kill adapter, driver will do last chance of
+ OCR to see if driver can bring back the FW.
+
+2. Add the support update flag to the driver to tell LSI megaraid_sas
+ application which driver will support the device update. So application
+ will not need to do the device update after application add/del the device
+ from the system.
+3. In driver's timeout routine, driver will do three time reset if fw is in
+ failed state. Driver will kill adapter if can't bring back FW after the
+ this three times reset.
+4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
+ customer can use the input paramenter max_sectors to add 1MB support to GEN2
+ controller.
