     hv_netvsc — Hyper-V Network Virtual Service Consumer


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

           device hyperv


     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 Hyper-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
     infrastructure provided by hv_vmbus(4) driver.  The VSP in the root partition then forwards
     the network related requests to the physical network card.

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


     FreeBSD support for hv_netvsc was first added by Microsoft BSD Integration Services Team
