Enhancements
************************

Major Changes and Enhancements from 2.05.11 (Native driver for RHEL 3 Update 2, EM64T)

• Increase the timeout in RAID Action Request from 2 to 10 seconds. Under stress conditions, the QUIESCE_PHYS_IO action request was taking longer than 2 seconds timeout to complete, thus resulting in the driver going into a host bus reset.
• Processing of an IOCStatus of MPI_IOCSTATUS_SCSI_RESIDUAL_MISMATCH was changed to allow the OS SCSI layer to retry the command.
• Search IOCPage3 for Id being a physical drive of a volume. If so, don’t include its information in Ioctl TargetInfo data.
• Allow Check Conditions to take precedence over data length checks in DATA_UNDERRUN error 
processing.
• Added code to obtain IOC Page 2 data in order to provide Volume data in Target Info Data 
returned by an IOCTL request.
• Fixed Target Info code to prevent overrunning the data buffer length provided by the 
application. Also fixed that code to include checking for the last id on the IOC.
• Added code in the data underrun response processing to return an error code if no data was transferred.
• Fixed code to allow Ioctl operation on IA64.
• Performance enhancements were made.
