.Dd July 16, 2005 .Dt NVE 4 .Os .Sh NAME .Nm nve .Nd "NVIDIA nForce MCP Networking Adapter device driver" .Sh SYNOPSIS To compile support for the .Nm driver into your kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device miibus" .Cd "device nve" .Ed
p Alternatively, to load the .Nm driver at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent if_nve_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the NVIDIA nForce MCP and nForce2 MCP2 networking adapter that is embedded in the southbridge of most nForce and nForce2 motherboards.
p This driver is a reimplementation of the NVIDIA supported Linux .Nm nvnet driver and uses the same closed source API library to access the underlying hardware. There is currently no programming documentation available for this device, and therefore little is known about the internal architecture of the MAC engine itself.
p The .Nm driver supports the following media types: l -tag -width ".Cm 10baseT/UTP" t Cm autoselect Enable autoselection of the media type and options. t Cm 10baseT/UTP Set 10Mbps operation. t Cm 100baseTX Set 100Mbps (Fast Ethernet) operation. .El
p The .Nm driver supports the following media options: l -tag -width ".Cm 10baseT/UTP" t Cm full-duplex Set full duplex operation. .El
p For more information on configuring this device, see .Xr ifconfig 8 . .Sh HARDWARE The .Nm driver supports the NVIDIA MCP onboard adapters of mainboards with the following chipsets:
p l -bullet -compact t nForce t nForce2 .El .Sh DIAGNOSTICS l -diag t "nve%d: couldn't map memory" A fatal initialization error has occurred. t "nve%d: couldn't map interrupt" A fatal initialization error has occurred. t "nve%d: failed to allocate memory" There are not enough mbufs available for allocation. t "nve%d: device timeout" The device has stopped responding to the network, or there is a problem with the network connection (cable). .El .Sh SEE ALSO .Xr arp 4 , .Xr miibus 4 , .Xr netintro 4 , .Xr ng_ether 4 , .Xr ifconfig 8 .Sh HISTORY The .Nm driver first appeared in .Fx 5.5 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Quinton Dolan Aq q@onthenet.com.au and .An "David E. O'Brien" Aq obrien@FreeBSD.org .
