sfc devlink support
|
||||
===================
|
||||
|

This document describes the devlink features implemented by the ``sfc``
|
||||
device driver for the ef100 device.
|

|
||||
Info versions
|
||||
=============
|
||||
|
||||
The ``sfc`` driver reports the following versions
|
||||
|

.. list-table:: devlink info versions implemented
|
||||
:widths: 5 5 90
|
||||
|
||||
* - Name
|
||||
- Type
|
||||
- Description
|
||||
* - ``fw.mgmt.suc``
|
||||
- running
|
||||
- For boards where the management function is split between multiple
|
||||
control units, this is the SUC control unit's firmware version.
|
||||
* - ``fw.mgmt.cmc``
|
||||
- running
|
||||
- For boards where the management function is split between multiple
|
||||
control units, this is the CMC control unit's firmware version.
|
||||
* - ``fpga.rev``
|
||||
- running
|
||||
- FPGA design revision.
|
||||
* - ``fpga.app``
|
||||
- running
|
||||
- Datapath programmable logic version.
|
||||
* - ``fw.app``
|
||||
- running
|
||||
- Datapath software/microcode/firmware version.
|
||||
* - ``coproc.boot``
|
||||
- running
|
||||
- SmartNIC application co-processor (APU) first stage boot loader version.
|
||||
* - ``coproc.uboot``

|
||||
multiple images (e.g. PXE and UEFI), this is the specifically the PXE boot
|
