34 .Nd "NVIDIA nForce MCP Networking Adapter device driver"
37 This driver is deprecated and will not be available in
40 Please consider using the
44 To compile this driver into the kernel,
45 place the following lines in your
46 kernel configuration file:
47 .Bd -ragged -offset indent
52 Alternatively, to load the driver as a
53 module at boot time, place the following line in
55 .Bd -literal -offset indent
61 driver provides support for the NVIDIA nForce MCP and nForce2 MCP2
62 networking adapter that is embedded in the southbridge of most
63 nForce and nForce2 motherboards.
65 This driver is a reimplementation of the NVIDIA supported Linux
67 driver and uses the same closed source API library to access
68 the underlying hardware.
69 There is currently no programming documentation available for this
70 device, and therefore little is known about the internal architecture
71 of the MAC engine itself.
75 driver supports the following media types:
76 .Bl -tag -width ".Cm 10baseT/UTP"
78 Enable autoselection of the media type and options.
82 Set 100Mbps (Fast Ethernet) operation.
84 Set 1000Mbps (Gigabit Ethernet) operation.
89 driver supports the following media options:
90 .Bl -tag -width ".Cm 10baseT/UTP"
92 Set full duplex operation.
95 For more information on configuring this device, see
100 driver supports the NVIDIA MCP onboard adapters of mainboards with
101 the following chipsets:
115 .It "nve%d: couldn't map memory"
116 A fatal initialization error has occurred.
117 .It "nve%d: couldn't map interrupt"
118 A fatal initialization error has occurred.
119 .It "nve%d: failed to allocate memory"
120 There are not enough mbufs available for allocation.
121 .It "nve%d: device timeout"
122 The device has stopped responding to the network, or there is a problem with
123 the network connection (cable).

148 There are reports that when the card is in auto select mode,
149 ifconfig output reports a 10baseT/UTP output while the LEDs and
150 bandwidth show that the card is actually in 100baseTX mode.
