*Use heuristics to guess HCI vendor extensions support in advance*

Type: ``bool``

Help
====

.. code-block:: none

    Use some heuristics to try to guess in advance whether the controller
    supports the HCI vendor extensions in advance, in order to prevent
    sending vendor commands to controller which may interpret them in
    completely different ways.
