DEVLINK-DEV(8) Linux DEVLINK-DEV(8) NAME devlink-dev - devlink device configuration SYNOPSIS devlink [ OPTIONS ] dev { COMMAND | help } OPTIONS := { -V[ersion] | -n[no-nice-names] } devlink dev show [ DEV ] devlink dev help devlink dev eswitch set DEV [ mode { legacy | switchdev } ] [ inline-mode { none | link | network | transport } ] [ encap { disable | enable } ] devlink dev eswitch show DEV devlink dev param set DEV name PARAMETER value VALUE cmode { runtime | driverinit | perma- nent } devlink dev param show [ DEV name PARAMETER ] devlink dev reload DEV DESCRIPTION devlink dev show - display devlink device attributes DEV - specifies the devlink device to show. If this argument is omitted all devices are listed. Format is: BUS_NAME/BUS_ADDRESS devlink dev eswitch show - display devlink device eswitch attributes devlink dev eswitch set - sets devlink device eswitch attributes mode { legacy | switchdev } Set eswitch mode legacy - Legacy SRIOV switchdev - SRIOV switchdev offloads 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. none - None link - L2 mode network - L3 mode transport - L4 mode encap { disable | enable } Set eswitch encapsulation support disable - Disable encapsulation support enable - Enable encapsulation support devlink dev param set - set new value to devlink device configuration parameter name PARAMETER Specify parameter name to set. value VALUE New value to set. cmode { runtime | driverinit | permanent } Configuration mode in which the new value is set. 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 configura- tion mode requires hard reset to apply the new value. devlink dev param show - display devlink device supported configuration parameters attributes name PARAMETER Specify parameter name to show. If this argument is omitted all parameters supported by devlink devices are listed. devlink dev reload - perform hot reload of the driver. DEV - Specifies the devlink device to reload. EXAMPLES devlink dev show Shows the state of all devlink devices on the system. devlink dev show pci/0000:01:00.0 Shows the state of specified devlink device. devlink dev eswitch show pci/0000:01:00.0 Shows the eswitch mode of specified devlink device. devlink dev eswitch set pci/0000:01:00.0 mode switchdev Sets the eswitch mode of specified devlink device to switchdev. devlink dev param show pci/0000:01:00.0 name max_macs Shows the parameter max_macs attributes. devlink dev param set pci/0000:01:00.0 name internal_error_reset value true cmode runtime Sets the parameter internal_error_reset of specified devlink device to true. devlink dev reload pci/0000:01:00.0 Performs hot reload of specified devlink device.
