    [SCSI] stex: fix id mapping issue · e0b2e597
    Ed Lin authored
    The correct internal mapping of stex controllers should be:
    id:0~15, lun:0~7 (st_shasta)
    id:0, lun:0~127 (st_yosemite)
    id:0~127, lun:0 (st_vsc and st_vsc1)
    
    This patch reports the internal mapping to scsi mid layer,  eliminating
    the translation between scsi mid layer and firmware. To achieve this
    goal, we also need to:
    -- fail the REPORT_LUNS command for st_shasta because the
       firmware is known to not report all actual luns
    -- add an entry in scsi_devindo.c to force sequential lun scan
       (for st_shasta controllers)
    -- fail the REPORT_LUNS command for console device
    -- remove special handling of REPORT_LUNS command for
       st_yosemite, as there is no translation mapping now
