37 devlink dev show - display devlink device attributes
38 DEV - specifies the devlink device to show. If this argument is omit‐
39 ted all devices are listed.
40 Format is:
42 BUS_NAME/BUS_ADDRESS
43 devlink dev eswitch show - display devlink device eswitch attributes
46 devlink dev eswitch set - sets devlink device eswitch attributes
47 mode { legacy | switchdev }
48 Set eswitch mode
49 legacy - Legacy SRIOV
51 switchdev - SRIOV switchdev offloads
53 inline-mode { none | link | network | transport }
56 Some HWs need the VF driver to put part of the packet headers on
57 the TX descriptor so the e-switch can do proper matching and
58 steering.
59 none - None
61 link - L2 mode
63 network - L3 mode
65 transport - L4 mode
67 encap { disable | enable }
70 Set eswitch encapsulation support
71 disable - Disable encapsulation support
73 enable - Enable encapsulation support
75 devlink dev param set - set new value to devlink device configuration
78 parameter
79 name PARAMETER
80 Specify parameter name to set.
81 value VALUE
84 New value to set.
85 cmode { runtime | driverinit | permanent }
88 Configuration mode in which the new value is set.
89 runtime - Set new value while driver is running. This configura‐
91 tion mode doesn't require any reset to apply the new value.
92 driverinit - Set new value which will be applied during driver
94 initialization. This configuration mode requires restart driver
95 by devlink reload command to apply the new value.
96 permanent - New value is written to device's non-volatile mem‐
98 ory. This configuration mode requires hard reset to apply the
99 new value.
100 devlink dev param show - display devlink device supported configuration
103 parameters attributes
104 name PARAMETER Specify parameter name to show. If this argument is
105 omitted all parameters supported by devlink devices are listed.
106 devlink dev reload - perform hot reload of the driver.
109 DEV - Specifies the devlink device to reload.
110 devlink dev info - display device information.
113 Display device information provided by the driver. This command can be
114 used to query versions of the hardware components or device components
115 which can't be updated ( fixed ) as well as device firmware which can
116 be updated. For firmware components running displays the versions of
117 firmware currently loaded into the device, while stored reports the
118 versions in device's flash. Running and stored versions may differ
119 after flash has been updated, but before reboot.
120 DEV - specifies the devlink device to show. If this argument is omit‐
123 ted all devices are listed.
124 devlink dev flash - write device's non-volatile memory.
127 DEV - specifies the devlink device to write to.
128 file PATH - Path to the file which will be written into device's flash.
130 The path needs to be relative to one of the directories searched by the
131 kernel firmware loaded, such as /lib/firmware.
132 component NAME - If device stores multiple firmware images in non-
134 volatile memory, this parameter may be used to indicate which firmware
135 image should be written. The value of NAME should match the component
136 names from devlink dev info and may be driver-dependent.

153 Shows the parameter max_macs attributes.
154 devlink dev param set pci/0000:01:00.0 name internal_error_reset value
156 true cmode runtime
157 Sets the parameter internal_error_reset of specified devlink device
158 to true.
