clang-format: re-format for clang-19 clang-format-19 isn't compatible with the clang-format-18 output, so we need to reformat the code with the latest version. A few parameters in clang-tidy have been deprecated, so adjust the style file accordingly. See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style. See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement. Change-Id: If08d21ecb3a52f1817ee7b3c7faae77cd527a34a Signed-off-by: Patrick Williams <patrick@stwcx.xyz>
There is the need to read a specific ethernet-level statistic value from the BMC. This is driven primarily to detect link errors that require hardware swaps during manufacturing.
This command will be well structured such that there is a request and response which mirror to some extent.
The request will specify the ethernet interface by name, as a length-prepended string, and the field they're requesting by identifier (an unsigned byte).
If the command is not supported, the IPMI OEM handler will respond accordingly, however, if the field is not supported or not recognized, the command will return 0xcc (invalid field).
The current ethernet statistics available (all future additions must append):
| Identifier | Human Readable Name |
|---|---|
| 0 | rx_bytes |
| 1 | rx_compressed |
| 2 | rx_crc_errors |
| 3 | rx_dropped |
| 4 | rx_errors |
| 5 | rx_fifo_errors |
| 6 | rx_frame_errors |
| 7 | rx_length_errors |
| 8 | rx_missed_errors |
| 9 | rx_nohandler |
| 10 | rx_over_errors |
| 11 | rx_packets |
| 12 | tx_aborted_errors |
| 13 | tx_bytes |
| 14 | tx_carrier_errors |
| 15 | tx_compressed |
| 16 | tx_dropped |
| 17 | tx_errors |
| 18 | tx_fifo_errors |
| 19 | tx_heartbeat_errors |
| 20 | tx_packets |
| 21 | tx_window_errors |
Request
| Byte(s) | Value | Data |
|---|---|---|
| 0x00 | Statistic ID | The identifier of the desired statistic. |
| 0x01 | Length | Length of string (not including null termination). |
| 0x02.. | The name | The string, not null-terminated. |
Response
| Byte(s) | Value | Data |
|---|---|---|
| 0x00 | Stat ID | The identifier of the desired statistic. |
| 0x01.... | Uint64 | The value. Because these are counters we don't anticipate negative values, and we don't expect overflow. |
