Original From: Ingo Flaschberger <if@xip.at> To support the RA4100 array from Compaq. This patch now correctly handles SCSI_UNKNOWN types with regard to BLIST_REPORTLUNS2 (allow it) and cdb[1] LUN inclusion (don't). It also allows a BLIST_MAX_512 flag to restrict the maximum transfer length to 512 blocks (apparently this is an RA4100 problem). Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
