CRU

normal

(normal, direct, macvtap)

The vnic type to be bound on the neutron port. To support SR-IOV PCI passthrough networking, you can request that the neutron port be realized as normal (virtual nic), direct (pci passthrough), or macvtap (virtual interface with a tap-like software interface). The ML2 plug-in supports the vnic_type.
