| |
| The ``ice`` driver reports the following versions |
| |
| .. list-table:: devlink info versions implemented |
| :widths: 5 5 5 90 |
| |
| * - Name |
| - Type |
| - Example |
| - Description |
| * - ``board.id`` |
| - fixed |
| - K65390-000 |
| - The Product Board Assembly (PBA) identifier of the board. |
| * - ``fw.mgmt`` |
| - running |
| - 2.1.7 |
| - 3-digit version number of the management firmware that controls the |
| PHY, link, etc. |
| * - ``fw.mgmt.api`` |
| - running |
| - 1.5 |
| - 2-digit version number of the API exported over the AdminQ by the |

| - 1.2581.0 |
| - Version of the Option ROM containing the UEFI driver. The version is |
| reported in ``major.minor.patch`` format. The major version is |
| incremented whenever a major breaking change occurs, or when the |
| minor version would overflow. The minor version is incremented for |
| non-breaking changes and reset to 1 when the major version is |
| incremented. The patch version is normally 0 but is incremented when |
| a fix is delivered as a patch against an older base Option ROM. |

| required to uniquely identify the package. |
| * - ``fw.netlist`` |
| - running |
| - 1.1.2000-6.7.0 |
| - The version of the netlist module. This module defines the device's |
| Ethernet capabilities and default settings, and is used by the |
| management firmware as part of managing link and device |
| connectivity. |
| * - ``fw.netlist.build`` |
| - running |
| - 0xee16ced7 |
| - The first 4 bytes of the hash of the netlist module contents. |

| |
| The ``ice`` driver enables access to the contents of the Non Volatile Memory |
| flash chip via the ``nvm-flash`` region. |
| |
| Users can request an immediate capture of a snapshot via the |
| ``DEVLINK_CMD_REGION_NEW`` |
