721 * number of Error characters received at any time.

723 * transitioned from "up" to "down" due to a local fault.

726 * XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
727 * to 4 x /E/ (i.e. a column containing all error characters), thus
728 * the statistic tracks the number of Error columns received at any
729 * time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
730 * to 1, then this stat increments when COLUMN2 is found within 'n'
731 * clocks after COLUMN1. Here, 'n' is defined by
732 * XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
733 * 0, then it means to search anywhere for COLUMN2).
