HYPER-V(4)		 BSD Kernel Interfaces Manual		    HYPER-V(4)

NAME
     hv_netvsc -- Hyper-V Network Virtual Service Consumer

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in the
     system kernel configuration file:

	   device hyperv

DESCRIPTION
     The hv_netvsc driver implements the virtual network device	for FreeBSD
     guest partitions running on Hyper-V.  FreeBSD guest partitions running on
     Hyper-V do	not have direct	access to network devices attached to the Hy-
     per-V server.  Although a FreeBSD guest can access	network	devices	using
     Hyper-V's full emulation mode, the	performance in this mode tends to be
     unsatisfactory.

     To	counter	the above issues, the hv_netvsc	driver implements a network
     Virtual Service Consumer (VSC) that relays	network	requests from the
     guest partition to	the network Virtual Service Provider (VSP) hosted in
     the root partition	using the high performance data	exchange infrastruc-
     ture provided by hv_vmbus(4) driver.  The VSP in the root partition then
     forwards the network related requests to the physical network card.

HISTORY
     Support for hv_netvsc first appeared in FreeBSD 10.0.  The	driver was de-
     veloped through a joint effort between Citrix Incorporated, Microsoft
     Corporation, and Network Appliance	Incorporated.

AUTHORS
     FreeBSD support for hv_netvsc was first added by Microsoft	BSD
     Integration Services Team <bsdic@microsoft.com>.
