Adding Rx rule for TCP or UDP
=============================

.. toctree::
	:hidden:

Check that Rx classification rule can redirect matching TCP/UDP traffic to a different Rx queue.

#. Create the first pair of connected sockets on IUT and Tester.

#. Compute RSS hash and predict the Rx queue **init_queue** that should process packets send from Tester over the first connection.

#. Find another pair of ports on IUT and Tester such that the same Rx queue will be used to receive packets if sockets are bound to these new ports.

#. Create the second pair of connected sockets on IUT and Tester bound to these new ports.

#. Send packets from Tester to IUT via the first connection, check that on IUT they are received by **init_queue** Rx queue.

#. Send packets from Tester to IUT via the second connection, check that on IUT they are received by **init_queue** Rx queue.

#. Add Rx classification rule directing packets received via the first connection to another Rx queue **new_queue**.

#. Send packets from Tester to IUT via the first connection, check that on IUT they are received by **new_queue** Rx queue.

#. Send packets from Tester to IUT via the second connection, check that on IUT they are received by **init_queue** Rx queue.
