Resource Scope Filtering
========================
When dumping resources for all devices, ``devlink resource show`` accepts
an optional ``scope`` parameter to restrict the response to device-level
resources, port-level resources, or both (the default).
To dump only device-level resources across all devices:
.. code:: shell
$ devlink resource show scope dev
pci/0000:03:00.0:
name max_local_SFs size 128 unit entry dpipe_tables none
name max_external_SFs size 128 unit entry dpipe_tables none
pci/0000:03:00.1:
name max_local_SFs size 128 unit entry dpipe_tables none
name max_external_SFs size 128 unit entry dpipe_tables none
To dump only port-level resources across all devices:
.. code:: shell
$ devlink resource show scope port
pci/0000:03:00.0/196608:
name max_SFs size 128 unit entry dpipe_tables none
pci/0000:03:00.0/196609:
name max_SFs size 128 unit entry dpipe_tables none
pci/0000:03:00.1/196708:
name max_SFs size 128 unit entry dpipe_tables none
pci/0000:03:00.1/196709:
name max_SFs size 128 unit entry dpipe_tables none
Note that port-level resources are read-only.
