REPORTER - specifies the reporter's name registered on the devlink device. devlink health dump clear - Delete the saved dump. Deleting the saved dump enables a generation of a new dump on the next "devlink health dump show" command. DEV - specifies the devlink device. REPORTER - specifies the reporter's name registered on the devlink device. devlink health set - Enable the user to configure: 1) grace_period [msec] - Time interval between consecutive auto recoveries. 2) auto_recover [true/false] - Indicates whether the devlink should execute automatic re- cover on error. Please note that this command is not supported on a reporter which doesn't support a re- covery method. DEV - specifies the devlink device.
