Hi Tim

Can you confirm the counter is this one:

                       /* Report late collisions as a frame error. */
                        if (status & (BD_ENET_RX_NO | BD_ENET_RX_CL))
                                ndev->stats.rx_frame_errors++;

I don't see anywhere else frame errors are counted, but it would be
good to prove we are looking in the right place.
