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

.. toctree::
	:hidden:

Check that Tx interrupt coalescing parameters are applied on a tested interface.



#. Check that Tx interrupt coalescing settings are supported.

#. Save current values of coalescing parameters changed by **profile**.

#. Disable adaptive Tx coalescing before changing Tx parameters.

#. Set Tx time and frame limits to zero

#. Set Tx interrupt coalescing parameters from **profile**.

#. Read back Tx coalescing parameters and check they were applied.
