Provide devlink .info_get callback to allow the driver to report
detailed version information. The following info is reported:
"serial_number" -> The PCI DSN of the adapter
"fw.mgmt" -> The version of the firmware
"fw.mgmt.api" -> The API version of interface exposed over the AdminQ
"fw.psid" -> The version of the NVM image
"fw.bundle_id" -> Unique identifier for the combined flash image
"fw.undi" -> The combo image version
With this, 'devlink dev info' provides at least the same amount
information as is reported by ETHTOOL_GDRVINFO:
$ ethtool -i enp2s0f0 | egrep '(driver|firmware)'
driver: i40e
firmware-version: 9.30 0x8000e5f3 1.3429.0
$ devlink dev info pci/0000:02:00.0
pci/0000:02:00.0:
driver i40e
serial_number c0-de-b7-ff-ff-ef-ec-3c
versions:
running:
fw.mgmt 9.130.73618
fw.mgmt.api 1.15
fw.psid 9.30
fw.bundle_id 0x8000e5f3
fw.undi 1.3429.0
