Subject: [PATCH net-next] i40e: Align devlink info versions with ice driver and add docs
Align devlink info versions with ice driver so change 'fw.mgmt'
version to be 2-digit version [major.minor], add 'fw.mgmt.build'
that reports mgmt firmware build number and use '"fw.psid.api'
for NVM format version instead of incorrect '"fw.psid'.
Additionally add missing i40e devlink documentation.
Fixes: 5a423552e0d9 ("i40e: Add handler for devlink .info_get")

+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.
