+ * other than the broadcast address.
+ * @tx_bcast_frms: Count of successfully transmitted frames to the broadcast

+ * Includes discarded frames that are not sent to the network.
+ * @tx_tagged_frms: Count of transmitted frames containing a VLAN tag.

+ * @tx_tcp: Count of transmitted TCP segments. Does not include segments
+ * containing retransmitted octets.
+ * @tx_rst_tcp: Count of transmitted TCP segments containing the RST flag.
+ * @tx_udp: Count of transmitted UDP datagrams.
+ * @tx_parse_error: Increments when the TPA is unable to parse a packet. This
+ * generally occurs when a packet is corrupt somehow, including
+ * packets that have IP version mismatches, invalid Layer 2 control
+ * fields, etc. L3/L4 checksums are not offloaded, but the packet
+ * is still be transmitted.
+ * @tx_unknown_protocol: Increments when the TPA encounters an unknown
+ * protocol, such as a new IPv6 extension header, or an unsupported
+ * Routing Type. The packet still has a checksum calculated but it
+ * may be incorrect.
+ * @tx_pause_ctrl_frms: Count of MAC PAUSE control frames that are transmitted.
+ * Since, the only control frames supported by this device are
+ * PAUSE frames, this register is a count of all transmitted MAC

+ * on this Aggregation port.
+ * @tx_lacpdu_frms: Count of LACPDUs transmitted on this Aggregation port.
+ * @tx_drop_ip: Count of transmitted IP datagrams that could not be passed to
+ * the network. Increments because of:
+ * 1) An internal processing error
+ * (such as an uncorrectable ECC error). 2) A frame parsing error
+ * during IP checksum calculation.
+ * @tx_marker_resp_pdu_frms: Count of Marker Response PDUs transmitted on this
+ * Aggregation port.
+ * @tx_xgmii_char2_match: Maintains a count of the number of transmitted XGMII
+ * characters that match a pattern that is programmable through
+ * register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
+ * is set to /T/ (i.e. the terminate character), thus the statistic
+ * tracks the number of transmitted Terminate characters.
+ * @tx_xgmii_char1_match: Maintains a count of the number of transmitted XGMII
+ * characters that match a pattern that is programmable through
+ * register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
+ * is set to /S/ (i.e. the start character),

+ * @tx_xgmii_column2_match: Maintains a count of the number of transmitted XGMII
+ * columns that match a pattern that is programmable through register
+ * XMAC_STATS_TX_XGMII_COLUMN2_PORTn. By default, the pattern is set
+ * to 4 x /E/ (i.e. a column containing all error characters), thus
+ * the statistic tracks the number of Error columns transmitted at
+ * any time. If XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is
+ * set to 1, then this stat increments when COLUMN2 is found within
+ * 'n' clocks after COLUMN1. Here, 'n' is defined by
+ * XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set
+ * to 0, then it means to search anywhere for COLUMN2).
+ * @tx_xgmii_column1_match: Maintains a count of the number of transmitted XGMII
+ * columns that match a pattern that is programmable through register
+ * XMAC_STATS_TX_XGMII_COLUMN1_PORTn. By default, the pattern is set

+ * thus the statistic tracks the number of transmitted Idle columns.
+ * @tx_any_err_frms: Count of transmitted frames containing any error that

+ * there is an ECC while reading the frame out of the transmit
+ * buffer. Also increments if the transmit protocol assist (TPA)
+ * block determines that the frame should not be sent.
+ * @tx_drop_frms: Count of frames that could not be sent for no other reason
+ * than internal MAC processing. Increments once whenever the
+ * transmit buffer is flushed (due to an ECC error on a memory
+ * descriptor).
+ * @rx_ttl_frms: Count of total received MAC frames, including frames received
+ * with frame-too-long, FCS, or length errors. This stat can be

+ * everything, even "frames" as small one byte of preamble.
+ * @rx_vld_frms: Count of successfully received MAC frames. Does not include

+ * @rx_offload_frms: Count of offloaded received frames that are passed to
+ * the host.
+ * @rx_ttl_octets: Count of total octets of received frames, not including

+ * internal switch because they did not have an entry in the
+ * Filtering Database. This includes frames that had an invalid
+ * destination MAC address or VLAN ID. It also includes frames are

+ * of the target VPATH.
+ * @rx_len_discard: Count of received frames that are discarded because of an
+ * invalid frame length (includes fragments, oversized frames and
+ * mismatch between frame length and length/type field). This stat
+ * can be configured

+ * receive traffic steering (RTS) steered the frame to the trash
+ * queue.
+ * @rx_buff_full_discard: Count of received frames that are discarded because
+ * internal buffers are full. Includes frames discarded because the
+ * RTS logic is waiting for an SSC lookup that has no timeout bound.
+ * Also, includes frames that are dropped because the MAC2FAU buffer
+ * is nearly full -- this can happen if the external receive buffer
+ * is full and the receive path is backing up.
+ * @rx_red_discard: Count of received frames that are discarded because of RED
+ * (Random Early Discard).
+ * @rx_xgmii_ctrl_err_cnt: Maintains a count of unexpected or misplaced control
+ * characters occuring between times of normal data transmission
+ * (i.e. not included in RX_XGMII_DATA_ERR_CNT). This counter is
+ * incremented when either -
+ * 1) The Reconciliation Sublayer (RS) is expecting one control
+ * character and gets another (i.e. is expecting a Start
+ * character, but gets another control character).
+ * 2) Start control character is not in lane 0
+ * Only increments the count by one for each XGMII column.
+ * @rx_xgmii_data_err_cnt: Maintains a count of unexpected control characters
+ * during normal data transmission. If the Reconciliation Sublayer
+ * (RS) receives a control character, other than a terminate control
+ * character, during receipt of data octets then this register is
+ * incremented. Also increments if the start frame delimiter is not
+ * found in the correct location. Only increments the count by one
+ * for each XGMII column.
+ * @rx_xgmii_char1_match: Maintains a count of the number of XGMII characters
+ * that match a pattern that is programmable through register
+ * XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
+ * to /E/ (i.e. the error character), thus the statistic tracks the
+ * number of Error characters received at any time.
+ * @rx_xgmii_err_sym: Count of the number of symbol errors in the received
+ * XGMII data (i.e. PHY indicates "Receive Error" on the XGMII).
+ * Only includes symbol errors that are observed between the XGMII
+ * Start Frame Delimiter and End Frame Delimiter, inclusive. And
+ * only increments the count by one for each frame.
+ * @rx_xgmii_column1_match: Maintains a count of the number of XGMII columns
+ * that match a pattern that is programmable through register
+ * XMAC_STATS_RX_XGMII_COLUMN1_PORTn. By default, the pattern is set
+ * to 4 x /E/ (i.e. a column containing all error characters), thus
+ * the statistic tracks the number of Error columns received at any
+ * time.
+ * @rx_xgmii_char2_match: Maintains a count of the number of XGMII characters
+ * that match a pattern that is programmable through register
+ * XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
+ * to /E/ (i.e. the error character), thus the statistic tracks the
+ * number of Error characters received at any time.
+ * @rx_local_fault: Maintains a count of the number of times that link
+ * transitioned from "up" to "down" due to a local fault.
+ * @rx_xgmii_column2_match: Maintains a count of the number of XGMII columns
+ * that match a pattern that is programmable through register
+ * XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
+ * to 4 x /E/ (i.e. a column containing all error characters), thus
+ * the statistic tracks the number of Error columns received at any
+ * time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
+ * to 1, then this stat increments when COLUMN2 is found within 'n'
+ * clocks after COLUMN1. Here, 'n' is defined by
+ * XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
+ * 0, then it means to search anywhere for COLUMN2).
+ * @rx_jettison: Count of received frames that are jettisoned because internal
+ * buffers are full.
+ * @rx_remote_fault: Maintains a count of the number of times that link
+ * transitioned from "up" to "down" due to a remote fault.
+ *
+ * XMAC Port Statistics.
