35  * struct xge_hal_stats_hw_info_t - Xframe hardware statistics.
36  * Transmit MAC Statistics:
37  *
38  * @tmac_frms: Count of successfully transmitted MAC
39  * frames Note that this statistic may be inaccurate. The correct statistic may
40  * be derived by calcualating (tmac_ttl_octets - tmac_ttl_less_fb_octets) / 8
41  *
42  * @tmac_data_octets: Count of data and padding octets of successfully
43  * transmitted frames.
44  *
45  * @tmac_drop_frms: Count of frames that could not be sent for no other reason
46  * than internal MAC processing. Increments once whenever the
47  * transmit buffer is flushed (due to an ECC error on a memory descriptor).
48  *
49  * @tmac_mcst_frms: Count of successfully transmitted frames to a multicast
50  * address. Does not include frames sent to the broadcast address.

53  * address.
54  *
55  * @tmac_pause_ctrl_frms: Count of MAC PAUSE control frames that are
56  * transmitted. Since, the only control frames supported by this device
57  * are PAUSE frames, this register is a count of all transmitted MAC control
58  * frames.

61  * framing characters.
62  *

67  * @tmac_any_err_frms: Count of transmitted frames containing any error that
68  * prevents them from being passed to the network. Increments if there is an ECC
69  * while reading the frame out of the transmit buffer.
70  *
71  * @tmac_ttl_less_fb_octets: Count of total octets of transmitted
72  * frames, not including framing characters (i.e. less framing bits)
73  *
74  * @tmac_vld_ip_octets: Count of total octets of transmitted IP datagrams that

76  * their padding counted as part of the IP datagram.
77  *
78  * @tmac_vld_ip: Count of transmitted IP datagrams that were passed to the
79  * network.
80  *
81  * @tmac_drop_ip: Count of transmitted IP datagrams that could not be passed to
82  * the network. Increments because of 1) an internal processing error (such as
83  * an uncorrectable ECC error); 2) a frame parsing error during IP checksum
84  * calculation.
85  *
86  * @tmac_icmp: Count of transmitted ICMP messages. Includes messages not sent
87  * due to problems within ICMP.
88  *
89  * @tmac_rst_tcp: Count of transmitted TCP segments containing the RST flag.

106  * not include frames received with frame-too-long or frame-too-short error.
107  *
108  * @rmac_drop_frms: Count of received frames that could not be passed to the
109  * host because of 1) Random Early Discard (RED); 2) Frame steering algorithm
110  * found no available queue; 3) Receive ingress buffer overflow.
