ice: add basic handler for devlink .info_get
The devlink .info_get callback allows the driver to report detailed version information. The following devlink versions are reported with this initial implementation: "fw.mgmt" -> The version of the firmware that controls PHY, link, etc "fw.mgmt.api" -> API version of interface exposed over the AdminQ "fw.mgmt.build" -> Unique build id of the source for the management fw "fw.undi" -> Version of the Option ROM containing the UEFI driver "fw.psid.api" -> Version of the NVM image format. "fw.bundle_id" -> Unique identifier for the combined flash image. "fw.app.name" -> The name of the active DDP package. "fw.app" -> The version of the active DDP package. With this, devlink dev info can report at least as much information as is reported by ETHTOOL_GDRVINFO. Compare the output from ethtool vs from devlink: $ ethtool -i ens785s0 driver: ice version: 0.8.1-k firmware-version: 0.80 0x80002ec0 1.2581.0 expansion-rom-version: bus-info: 0000:3b:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes $ devlink dev info pci/0000:3b:00.0 pci/0000:3b:00.0: driver ice serial number 00-01-ab-ff-ff-ca-05-68 versions: running: fw.mgmt 2.1.7 fw.mgmt.api 1.5 fw.mgmt.build 0x305d955f fw.undi 1.2581.0 fw.psid.api 0.80 fw.bundle_id 0x80002ec0 fw.app.name ICE OS Default Package fw.app 1.3.1.0 More pieces of information can be displayed, each version is kept separate instead of munged together, and each version has an identifier which comes with associated documentation.

+===================
+ice devlink support
+===================
+
+This document describes the devlink features implemented by the ``ice``
+device driver.
+
+Info versions
+=============
+
+The ``ice`` driver reports the following versions
+
+.. list-table:: devlink info versions implemented
+ :widths: 5 5 5 90
+
+ * - Name
+ - Type
+ - Example
+ - Description
+ * - ``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
+ management firmware. Used by the driver to identify what commands
+ are supported.
+ * - ``fw.mgmt.build``
+ - running
+ - 0x305d955f
+ - Unique identifier of the source for the management firmware.
+ * - ``fw.undi``
+ - running
+ - 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.
+ * - ``fw.psid.api``
+ - running
+ - 0.80
+ - Version defining the format of the flash contents.
+ * - ``fw.bundle_id``
+ - running
+ - 0x80002ec0
+ - Unique identifier of the firmware image file that was loaded onto
+ the device. Also referred to as the EETRACK identifier of the NVM.
+ * - ``fw.app.name``
+ - running
+ - ICE OS Default Package
+ - The name of the DDP package that is active in the device. The DDP
+ package is loaded by the driver during initialization. Each varation
+ of DDP package shall have a unique name.
+ * - ``fw.app``
+ - running
+ - 1.3.1.0
+ - The version of the DDP package that is active in the device. Note
+ that both the name (as reported by ``fw.app.name``) and version are
+ required to uniquely identify the package.
