veb interface
WARNING: The veb(4) man page says:
The veb pseudo-device supports the creation of a single layer 2 Ethernet network between multiple ports. Ethernet interfaces are added to the veb bridge to be used as ports. Unlike bridge(4), veb takes over the operation of the interfaces that are added as ports. They are then independent of the host network stack: the individual Ethernet ports no longer function as independent devices and cannot be configured with inet(4) or inet6(4) addresses or other layer-3 features themselves.
