OBJECT
dev - devlink device.
port - devlink port.
monitor
- watch for netlink messages.
sb - devlink shared buffer configuration.
resource
- devlink device resource configuration.
region - devlink address region access
health - devlink reporting and recovery
trap - devlink trap configuration
COMMAND
Specifies the action to perform on the object. The set of
possible actions depends on the object type. As a rule, it is
possible to show (or list ) objects, but some objects do not allow
all of these operations or have some additional commands. The help
command is available for all objects. It prints out a list of
available commands and argument syntax conventions.
If no command is given, some default command is assumed. Usually
it is list or, if the objects of this class cannot be listed,
help.
Exit status is 0 if command was successful or a positive integer
upon failure.
