OK try this. It doesn't seem to break anything on my test rig.
Move case 03 out from where it was.
                        case 0x3:                       /* TE state F3:
Deactivated */
                        /* If we're in F3 receiving INFO0, start T3 and
jump to F4 */
                        if (state & V_INFO0) {  /* Activate and start
timer */
                                b4xxp_setreg_ra(b4, R_ST_SEL, s->port,
A_ST_WR_STA, V_ST_ACT_ACTIVATE);
                                s->hfc_timers[HFC_T3] = b4->ticks +
timer_3_ms;
                                s->hfc_timer_on[HFC_T3] = 1;
                                if (DBG_ST)
                                        dev_info(b4->dev, "port %d:
receiving INFO0 in state 3, setting T3 and jumping to F4\n", s->port + 1);
                                hfc_force_st_state(b4, s->port, 4, 1);
                        }
                        /* Otherwise the network has shut us down */
                        else {
                                b4xxp_setreg_ra(b4, R_ST_SEL, s->port,
A_ST_WR_STA, V_ST_ACT_DEACTIVATE);
                                s->hfc_timer_on[HFC_T3] = 0;
                                hfc_force_st_state(b4, s->port, 3, 1);

                        }
                        s->newalarm = 0;
                        break;

and then remove the code in the test for !nt and sta=3 and INFO0 lower
down as we have already done it.
V_ST_ACT_(DE)ACTIVATE are the 40 and 60 you see.
