This driver is a reimplementation of the NVIDIA supported Linux 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. .Pp The .Nm driver supports the following media types: .Pp .Bl -tag -width xxxxxxxxxxxxxxxxxxxx .It autoselect Enable autoselection of the media type and options .It 10baseT/UTP Set 10Mbps operation .It 100baseTX Set 100Mbps (fast ethernet) operation .El .Pp The .Nm driver supports the following media options: .Pp .Bl -tag -width xxxxxxxxxxxxxxxxxxxx .It full-duplex Set full duplex operation .El .Pp Note that the nForce3 MCP3 may also work when run in 32/64bit compatibility mode but as yet has not been tested. For further information on configuring this device, see .Xr ifconfig 8 . .Pp .Sh DIAGNOSTICS .Bl -diag .It "nv%d: couldn't map memory" A fatal initialization error has occurred. .It "nv%d: couldn't map interrupt" A fatal initialization error has occurred. .It "nv%d: failed to allocate memory" There are not enough mbuf's available for allocation. .It "nv%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 AUTHORS .An -nosplit The .Nm device driver was written by .An Quinton Dolan .
