+ * The following items are used for the abnormal errors statistics in
+ * the Tx datapath. When upper level application calls the
+ * rte_eth_tx_burst API function to send multiple packets at a time with
+ * burst mode based on hns3 network engine, there are some abnormal
+ * conditions that cause the driver to fail to operate the hardware to
+ * send packets correctly.
+ * Note: When using burst mode to call the rte_eth_tx_burst API function
+ * to send multiple packets at a time. When the first abnormal error is
+ * detected, add one to the relevant error statistics item, and then
+ * exit the loop of sending multiple packets of the function. That is to
+ * say, even if there are multiple packets in which abnormal errors may
+ * be detected in the burst, the relevant error statistics in the driver
+ * will only be increased by one.
+ * The detail description of the Tx abnormal errors statistic items as
+ * below:
+ * - over_length_pkt_cnt
+ * Total number of greater than HNS3_MAX_FRAME_LEN the driver
+ * supported.
+ *
+ * - exceed_limit_bd_pkt_cnt
+ * Total number of exceeding the hardware limited bd which process
+ * a packet needed bd numbers.
+ *
+ * - exceed_limit_bd_reassem_fail
+ * Total number of exceeding the hardware limited bd fail which
+ * process a packet needed bd numbers and reassemble fail.
+ *
+ * - unsupported_tunnel_pkt_cnt
+ * Total number of unsupported tunnel packet. The unsupported tunnel
+ * type: vxlan_gpe, gtp, ipip and MPLSINUDP, MPLSINUDP is a packet
+ * with MPLS-in-UDP RFC 7510 header.
+ *
+ * - queue_full_cnt
+ * Total count which the available bd numbers in current bd queue is
+ * less than the bd numbers with the pkt process needed.
+ *
+ * - pkt_padding_fail_cnt
+ * Total count which the packet length is less than minimum packet
+ * size HNS3_MIN_PKT_SIZE and fail to be appended with 0.
