2 Current Version : 00.00.04.01

3 Older Version   : 00.00.03.22



1. Add the new controller (0078, 0079) support to the driver

       Those controllers are LSI's next generatation(gen2) SAS controllers.

2 Current Version : 00.00.03.22

3 Older Version   : 00.00.03.20



1. Add shutdown DCMD cmd to the shutdown routine to make FW shutdown proper.

2. Unexpected interrupt occurs in HWR Linux driver, add the dumy readl pci flush will fix this issue.
