scsi: hisi_sas: allocate different SAS address for directly attached situation
In commit 8b8d66531555 ("scsi: hisi_sas: make SAS address of SATA disks unique"), we ensured that each SATA disk in the system has a unique SAS address, even if it is fake. That was for v2 hw. Add this for v3 hw. Signed-off-by: Xiang Chen <chenxiang66@hisilicon.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
