Devlink configuration parameters
|
||
|
|
================================
|
||
|
|
Following is the list of configuration parameters via devlink interface.
|
||
|
|
Each parameter can be generic or driver specific and are device level
|
||
|
|
parameters.
|
||
|
|
|
||
|
|
Note that the driver-specific files should contain the generic params
|
||
|
|
they support to, with supported config modes.
|
||
|
|
|
||
|
|
Each parameter can be set in different configuration modes:
|
||
|
|
runtime - set while driver is running, no reset required.
|
||
|
|
driverinit - applied while driver initializes, requires restart
|
||
|
|
driver by devlink reload command.
|
||
|
|
permanent - written to device's non-volatile memory, hard reset
|
||
|
|
required.
|
||
|
|
|
||
|
