    tcm_qla2xxx: Add fabric_prot_type attribute support · 64b16887
    Nicholas Bellinger authored
    This patch updates qla2xxx target to add a new fabric_prot_type TPG
    attribute, used for controlling LLD level protection into LIO when
    the backend device does not support T10-PI.
    
    This is required for qla_target.c to enable WRITE_STRIP + READ_INSERT
    hardware offloads.
    
    It's disabled by default and controls which se_sesion->sess_prot_type
    are set at tcm_qla2xxx_check_initiator_node_acl() session registration
    time.
