*Number of tx control buffers to be available across all connections*

Type: ``int``

Help
====

.. code-block:: none

    Set the number control buffers that is to be available for tx.
    This defines the size of the pool of tx buffers available
    for control procedure tx. This pool is shared across all
    procedures/connections with allocation through a fifo queue.
    Configure between 0 and (4 - BT_CTLR_LLCP_PER_CONN_TX_CTRL_BUF_NUM) * BT_CTLR_LLCP_CONN
