PATCH 3/3 tcm_loop: Enable 32-byte CDB support in virtual SCSI LLD

From: Nicholas Bellinger <[email protected]>

This patch changes tcm_loop_core.h:TL_SCSI_MAX_CMD_LEN=32 to enable the support of

Quoted 1 line

16 byte CDB within the TCM_Loop virtual SCSI fabric module. This value is used in

tcm_loop_fabric_scsi.c:tcm_loop_driver_probe() for struct Scsi_Host->max_cmd_len to signal Linux/SCSI of the maximum sized CDBs the LLD is capable of handling.
