tcm_qla2xxx: Add fabric_prot_type attribute support

Browse source

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.
