Sumant - this should be fixed post Beta. Chip, do we need another bugzilla to
track this change, or maybe not?

I think it would be good to have a new bugzilla to track two issues with megaraid:

1.  Version number is wrong.
2.  Throttle I/O patch.

commit 05e9ebbefb379a4da782b21b8427c88ac28a2334

    [SCSI] megaraid_sas: intercept cmd timeout and throttle io
    
    eh_timed_out call back (megasas_reset_timer) is used to throttle io
    to the adapter when it is called the first time for a scmd.
    The MEGASAS_FW_BUSY flag is set and can_queue reduced to 16.
    The can_queue is restored from completion routine in following
    two conditions : 5 seconds has elapsed and
    the # of outstanding cmds in FW is < 17.
