DESCRIPTION

DEV - specifies the devlink device to show. If this argument is omitted all devices are listed.


Format is:
BUS_NAME/BUS_ADDRESS

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

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.

name PARAMETER Specify parameter name to show. If this argument is omitted all parameters supported by devlink devices are listed.

DEV - Specifies the devlink device to reload.
