+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``
+     - running
+     - SmartNIC application co-processor (APU) co-operating system loader version.
+   * - ``coproc.main``
+     - running
+     - SmartNIC application co-processor (APU) main operating system version.
+   * - ``coproc.recovery``
+     - running
+     - SmartNIC application co-processor (APU) recovery operating system version.
+   * - ``fw.exprom``
+     - running
+     - Expansion ROM version. For boards where the expansion ROM is split between
+       multiple images (e.g. PXE and UEFI), this is the specifically the PXE boot
+       ROM version.
+   * - ``fw.uefi``
+     - running
+     - UEFI driver version (No UNDI support).
