NAME
     vsw - virtual network switch

SYNOPSIS
     vsw* at cbus?
     vnet* at vsw?

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

     The vsw driver supports version 1.0 of the vNet protocol.
