separated_cpu device parameter
==============================

.. toctree::
	:hidden:

Check that **separated_cpu** device parameter can be retrieved and changed via devlink API.

Scenarios: X3-DLV005, X3-DLV007.



#. If **if_down** is ``TRUE``, set IUT interface down.

#. Check that **separated_cpu** parameter value can be retrieved for the IUT interface.

#. Set **dist_layout** parameter to ``1``, so that receive queue has separated layout. Only then **separated_cpu** parameter is meaningful, it determines to which CPU receive queue events processing is assigned.

#. Check that **separated_cpu** parameter can be changed.
