This patch updates iscsi/iser-target to add a new fabric_prot_type TPG attribute for iser-target, used for controlling LLD level protection into LIO when the backend device does not support T10-PI. This is required for ib_isert to enable WRITE_STRIP + READ_INSERT hardware offloads. It's disabled by default and controls which se_sesion->sess_prot_type are set at iscsi_target_locate_portal() session registration time.
