====================
i40e devlink support
====================
This document describes the devlink features implemented by the ``i40e``
device driver.
Info versions
=============
The ``i40e`` driver reports the following versions
.. list-table:: devlink info versions implemented
:widths: 5 5 5 90
* - Name
- Type
- Example
- Description
* - ``board.id``
- fixed
- K15190-000
- The Product Board Assembly (PBA) identifier of the board.
* - ``fw.mgmt``
- running
- 9.130
- 2-digit version number of the management firmware that controls the
PHY, link, etc.
* - ``fw.mgmt.api``
- running
- 1.15
- 2-digit version number of the API exported over the AdminQ by the
management firmware. Used by the driver to identify what commands
are supported.
* - ``fw.mgmt.build``
- running
- 73618
- Build number of the source for the management firmware.
* - ``fw.undi``
- running
- 1.3429.0
- 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.
* - ``fw.psid.api``
- running
- 9.30
- Version defining the format of the flash contents.
* - ``fw.bundle_id``
- running
- 0x8000e5f3
- Unique identifier of the firmware image file that was loaded onto
the device. Also referred to as the EETRACK identifier of the NVM.
