+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."
