The Datagram Congestion Control Protocol (DCCP) must be disabled if it's not
needed. Neither Ubuntu 14.04 or openstack-ansible utilizes this kernel
module and the Ansible tasks will disable it by default.
To opt-out of this change, simply change the following variable to ``no``:
.. code-block:: yaml
disable_module['dccp']: no
**NOTE:** The module will be disabled on the next reboot.
