DEV - specifies the devlink device to show. If this argument is omitted all devices are listed.
Format is:
BUS_NAME/BUS_ADDRESS
legacy - Legacy SRIOV
switchdev - SRIOV switchdev offloads
none - None
link - L2 mode
network - L3 mode
transport - L4 mode
none - Disable encapsulation support
basic - Enable encapsulation support
runtime - Set new value while driver is running. This configuration mode doesn't require any reset to apply the new value.
driverinit - Set new value which will be applied during driver initialization. This configuration mode requires restart driver by devlink reload command to apply the new value.
permanent - New value is written to device's non-volatile memory. This configuration mode requires hard reset to apply the new value.
name PARAMETER Specify parameter name to show. If this argument is omitted all parameters supported by devlink devices are listed.
DEV - Specifies the devlink device to reload.
netns { PID | NAME | ID } - Specifies the network namespace to reload into, either by pid, name or id.
Display device information provided by the driver. This command can be used to query versions of the hardware components or device components which can't be updated ( fixed ) as well as device firmware which can be updated. For firmware components running displays the versions of firmware currently loaded into the device, while stored reports the versions in device's flash. Running and stored versions may differ after flash has been updated, but before reboot.
DEV - specifies the devlink device to show. If this argument is omitted all devices are listed.
DEV - specifies the devlink device to write to.
file PATH - Path to the file which will be written into device's flash. The path needs to be relative to one of the directories searched by the kernel firmware loaded, such as /lib/firmware.
component NAME - If device stores multiple firmware images in non-volatile memory, this parameter may be used to indicate which firmware image should be written. The value of NAME should match the component names from devlink dev info and may be driver-dependent.
