Overview

The vsw driver provides a network switch using the services provided by the UltraSPARC Hypervisor as found on sun4v systems. It attaches a separate vnet(4) interface for each switch port. These ports can be added to a bridge(4) or veb(4) to create a functional network switch.

The vsw driver supports version 1.0 of the vNet protocol.

History

The vsw driver first appeared in OpenBSD 4.7.
