/*
 * DF-4400: no local trigger exists — the defect needs the 3ware controller to
 * emit a duplicate/stale response word. This stub documents the exact word the
 * firmware controls (struct tws_outbound_response, tws_hdm.h:348-353):
 *
 *   bit 0    not_mfa    = 1   (response carries a request id, not an MFA)
 *   bits 8..15 status   = 0
 *   bits16..31 request_id = <stale in-range id, e.g. of an already-completed
 *                           SCSI IO slot>
 *
 * Delivered via the outbound FIFO, tws_get_response() (tws_hdm.c:354) hands it
 * to tws_intr_resp() (tws_cam.c:1161) which calls sc->reqs[id].cb() with no
 * state validation -> double xpt_done / NULL cb call.
