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 | permanent }
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 configuration 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
devlink dev show pci/0000:01:00.0
devlink dev eswitch show pci/0000:01:00.0
devlink dev eswitch set pci/0000:01:00.0 mode switchdev
devlink dev param show pci/0000:01:00.0 name max_macs
devlink dev param set pci/0000:01:00.0 name internal_error_reset value true cmode runtime
devlink dev reload pci/0000:01:00.0
