i40e: Do not call devlink_port_type_clear()

2023-11-07T00:16:13Z

Do not call devlink_port_type_clear() prior devlink port unregister and let devlink core to take care about it. Reproducer: [root@host ~]# rmmod i40e [ 4539.964699] i40e 0000:02:00.0: devlink port type for port 0 cleared without a software interface reference, device type not supported by the kernel? [ 4540.319811] i40e 0000:02:00.1: devlink port type for port 1 cleared without a software interface reference, device type not supported by the kernel?

i40e: Align devlink info versions with ice driver and add docs

2023-10-19T16:03:56Z

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.

i40e: Add handler for devlink .info_get

2023-10-15T13:33:41Z

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 Signed-off-by: Ivan Vecera Signed-off-by: David S.

i40e: Add initial devlink support

2023-10-15T13:33:41Z

Add an initial support for devlink interface to i40e driver. Similarly to ice driver the implementation doe not enable devlink to manage device-wide configuration and devlink instance is created for each physical function of PCIe device. Signed-off-by: Ivan Vecera Signed-off-by: David S. Miller
