The connection to the device may operate in one of a number of different
modes, :term:`VEPA` (either :term:`802.1Qbg` or :term:`802.1Qbh`),
passthrough (exclusive assignment of the host NIC) or bridge (ethernet
layer bridging of traffic). The passthrough mode would be used when there
is a network device which needs to have a MAC address or VLAN
configuration. For passthrough of network devices without MAC/VLAN
configuration, :class:`~os_vif.objects.vif.VIFHostDevice` should be used
instead.
