========================

.. toctree::
	:hidden:

	group_usecases-stats_reset-run.rst

Check the correctness of statistics reset

#. Initialize EAL

#. Start the Ethernet device

#. Prepare **tmpl** for test

#. Change **tst_if** MTU and **iut_port** MTU to be able to transmit or receive bigger frames if required

#. If running in "speed-up" mode, await stats reappearance holding numbers valid for the previous (test) iteration in order to pick those numbers (if any) as initial ones (instead of getting zeroes) to calculate the difference

#. Ensure that interface is UP on Tester side

#. Transmit and sniff **nb_pkts** packets from **tst_if**

#. Receive packets on **iut_port** and check that they match the sent ones

#. Wait statistics update

#. Check that general statistics are correct

#. Check that extended statistics are correct

#. Reset general stats statistics

#. Check that general statistics are correct

#. Reset extended stats statistics

#. Check that extended statistics are correct
