DESCRIPTION

33   devlink dev show - display devlink device attributes
34       DEV - specifies the devlink device to show.  If this argument is omit‐
35       ted all devices are listed.
36
37           Format is:
38             BUS_NAME/BUS_ADDRESS
39
40
41   devlink dev eswitch show - display devlink device eswitch attributes
42   devlink dev eswitch set - sets devlink device eswitch attributes
43       mode { legacy | switchdev }
44              Set eswitch mode
45
46              legacy - Legacy SRIOV
47
48              switchdev - SRIOV switchdev offloads
49
50
51       inline-mode { none | link | network | transport }
52              Some HWs need the VF driver to put part of the packet headers on
53              the TX descriptor so the e-switch can do proper matching and
54              steering.
55
56              none - None
57
58              link - L2 mode
59
60              network - L3 mode
61
62              transport - L4 mode
63
64
65       encap { disable | enable }
66              Set eswitch encapsulation support
67
68              disable - Disable encapsulation support
69
70              enable - Enable encapsulation support
71
72
73   devlink dev param set - set new value to devlink device configuration
74       parameter
75       name PARAMETER
76              Specify parameter name to set.
77
78
79       value VALUE
80              New value to set.
81
82
83       cmode { runtime | driverinit | permanent }
84              Configuration mode in which the new value is set.
85
86              runtime - Set new value while driver is running. This configura‐
87              tion mode doesn't require any reset to apply the new value.
88
89              driverinit - Set new value which will be applied during driver
90              initialization. This configuration mode requires restart driver
91              by devlink reload command to apply the new value.
92
93              permanent - New value is written to device's non-volatile mem‐
94              ory. This configuration mode requires hard reset to apply the
95              new value.
96
97
98   devlink dev param show - display devlink device supported configuration
99       parameters attributes
100       name PARAMETER Specify parameter name to show.  If this argument is
101       omitted all parameters supported by devlink devices are listed.
102
103
104   devlink dev reload - perform hot reload of the driver.
105       DEV - Specifies the devlink device to reload.
