BUS_NAME/BUS_ADDRESS
+.SS devlink dev eswitch show - display devlink device eswitch attributes
+.SS devlink dev eswitch set - sets devlink device eswitch attributes
+
+.TP
+.BR mode " { " legacy " | " switchdev " } "
+Set eswitch mode
+
+.I legacy
+- Legacy SRIOV
+
+.I switchdev
+- SRIOV switchdev offloads
+
+.TP
+.BR inline-mode " { " none " | " link " | " network " | " transport " } "
+Some HWs need the VF driver to put part of the packet headers on the TX descriptor so the e-switch can do proper matching and steering.
+
+.I none
+- None
+
+.I link
+- L2 mode
+
+.I network
+- L3 mode
+
+.I transport
+- L4 mode
+
+.TP
+.BR encap-mode " { " none " | " basic " } "
+Set eswitch encapsulation support
+
+.I none
+- Disable encapsulation support
+
+.I basic
+- Enable encapsulation support
+
+.SS devlink dev param set - set new value to devlink device configuration parameter
+
+.TP
+.BI name " PARAMETER"
+Specify parameter name to set.
+
+.TP
+.BI value " VALUE"
+New value to set.
+
+.TP
+.BR cmode " { " runtime " | " driverinit " | " permanent " } "
+Configuration mode in which the new value is set.
+
+.I runtime
+- Set new value while driver is running. This configuration mode doesn't require any reset to apply the new value.
+
+.I 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.
+
+.I permanent
+- New value is written to device's non-volatile memory. This configuration mode requires hard reset to apply the new value.
+
+.SS devlink dev param show - display devlink device supported configuration parameters attributes
+
+.BR name
+.IR PARAMETER
+Specify parameter name to show.
+If this argument is omitted all parameters supported by devlink devices are listed.
+
+.SS devlink dev reload - perform hot reload of the driver.
+
+.PP
+.I "DEV"
+- Specifies the devlink device to reload.
+
+.BR netns
+.BI { " PID " | " NAME " | " ID " }
+- Specifies the network namespace to reload into, either by pid, name or id.
+
+.SS devlink dev info - display device information.
+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 (
+.I fixed
+) as well as device firmware which can be updated. For firmware components
+.I running
+displays the versions of firmware currently loaded into the device, while
+.I stored
+reports the versions in device's flash.
+.I Running
+and
+.I stored
+versions may differ after flash has been updated, but before reboot.
+
+.PP
+.I "DEV"
+- specifies the devlink device to show.
+If this argument is omitted all devices are listed.
+
+.SS devlink dev flash - write device's non-volatile memory.
+
+.PP
+.I "DEV"
+- specifies the devlink device to write to.
+
+.BR file
+.I 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.
+
+.BR component
+.I 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
+.I NAME
+should match the component names from
+.B "devlink dev info"
+and may be driver-dependent.
