[SCSI] tcm_loop: Add multi-fabric Linux/SCSI LLD fabric module This patch adds the TCM_Loop Linux/SCSI LLD fabric module for accessing TCM device backstores as locally accessable SCSI LUNs in virtual SAS, FC, and iSCSI Target ports using the generic fabric TransportID and Target Port WWN naming handlers from TCM's target_core_fabric_lib.c The TCM_Loop module uses the generic fabric configfs infratructure provided by target_core_fabric_configfs.c and adds a module dependent attribute for the creation/release of the virtual I_T Nexus connected the TCM_Loop Target and Initiator Ports. TCM_Loop can also be used with scsi-generic and BSG drivers so that STGT userspace fabric modules, QEMU-KVM and other hypervisor SCSI passthrough support can access TCM device backstore and control CDB emulation.

tcm_loop: bump max_sectors There is not reason to artifically limit max_sectors in tcm_loop, set it to UINT_MAX to allow stressing the large I/O handling in the target core using the loopback driver. Also remove various superflous defines hiding the values set in the host template. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

loopback: Add fabric_prot_type attribute support This patch updates loopback 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. Also, go ahead and set DIN_PASS + DOUT_PASS so target-core knows that it will be doing any WRITE_STRIP and READ_INSERT operations.

tcm_loop: Fix wrong I_T nexus association tcm_loop has the I_T nexus associated with the HBA. This causes commands to become misdirected if the HBA has more than one target portal group; any command is then being sent to the first target portal group instead of the correct one. The nexus needs to be associated with the target portal group instead.
