+2 Current Version : 00.00.02.04
+3 Older Version   : 00.00.02.04 
+
+i.	Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
+	During initialization, depending on the device id, the template members 
+	are initialized with function pointers specific to the ppc or 
+	xscale controllers.

+i.	Register 16 byte CDB capability with scsi midlayer 
+
+	"Ths patch properly registers the 16 byte command length capability of the 
+	megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 
+	hardware supports 16 byte CDB's."
