*Number of incoming ACL data buffers*

Type: ``int``

Help
====

.. code-block:: none

    Number or incoming ACL data buffers sent from the Controller to the
    Host.
    In a combined Host and Controller build the buffers are shared and
    therefore Controller to Host flow control is not needed.
    In a Host only build with Controller to Host flow control enabled
    the Host will inform the Controller about the maximum number of
    buffers by setting this value in the Host Buffer Size command.
    When Controller to Host flow control is not enabled the Controller
    can assume that the Host has infinite amount of buffers.
