Added support in SR-IOV agent for ``accelerator-direct`` VNIC
type. This type represents a port that supports any kind of
hardware acceleration and is provided by Cyborg
(https://wiki.openstack.org/wiki/Cyborg). `RFE: 1909100
<https://bugs.launchpad.net/neutron/+bug/1909100>`_.
``accelerator-direct-physical`` is still not supported.
