porters.
Displays info about reporters registered on devlink devices and ports.
DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.
REPORTER - specifies the reporter's name registered on specified de-
vlink device or port.
devlink health recover - Initiate a recovery operation on a reporter.
This action performs a recovery and increases the recoveries counter on
success.

devlink health dump show - Display the last saved dump.
devlink health saves a single dump per reporter. If an dump is
not already stored by the Devlink, this command will generate a new
dump. The dump can be generated either automatically when a
reporter reports on an error or manually at the user's request.

DEV/PORT_INDEX - specifies the devlink port.
REPORTER - specifies the reporter's name registered on specified de-
vlink device or port.

Deleting the saved dump enables a generation of a new dump on
the next "devlink health dump show" command.
DEV - specifies the devlink device.
DEV/PORT_INDEX - specifies the devlink port.
REPORTER - specifies the reporter's name registered on specified de-
vlink device or port.

REPORTER - specifies the reporter's name registered on specified de-
vlink device or port.
