This feature is targeted to address the requirement to have independent patch release for firmware. Prior to 3.2.3, releasing a patch fix for firmware requires changes to bfa, to use new firmware images. But with these changes, if the new firmware is flashed on to the HBA with brocade adapter management utilites, driver uses the new firmware after checking the patch release byte in the firmware version.
