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.

[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.
