*Maximum number of pending TX buffers with a callback*

Type: ``int``

Help
====

.. code-block:: none

    Maximum number of pending TX buffers that have an associated
    callback. Normally this can be left to the default value, which
    is equal to the number of TX buffers in the stack-internal pool.
