[SCSI] aacraid: Greater than 2TB capacity support
Received from Mark Salyzyn from Adaptec. There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them. The problem is, once they are created, the driver will not be able to access the devices correctly without this patch.
