39 .Nd "AMD PCnet/PCI Fast Ethernet device driver"
41 To compile this driver into the kernel,
42 place the following lines in your
43 kernel configuration file:
44 .Bd -ragged -offset indent
49 Alternatively, to load the driver as a
50 module at boot time, place the following line in
52 .Bd -literal -offset indent
58 driver provides support for PCI Ethernet adapters and embedded
59 controllers based on the AMD PCnet/FAST, PCnet/FAST+, PCnet/FAST III,
60 PCnet/PRO and PCnet/Home Ethernet controller chips.
61 Supported NIC's include the Allied Telesyn AT-2700 family.
63 The PCnet/PCI chips include a 100Mbps Ethernet MAC and support
64 both a serial and MII-compliant transceiver interface.
65 They use a bus master DMA and a scatter/gather descriptor scheme.
66 The AMD chips provide a mechanism for zero-copy receive,
67 providing good performance in server environments.
68 Receive address filtering is provided using a single perfect filter entry
69 for the station address and a 64-bit multicast hash table.
73 driver supports the following media types:
75 .Bl -tag -width 10baseTXUTP
77 Enable autoselection of the media type and options.
78 The user can manually override
79 the autoselected mode by adding media options to
86 option can also be used to select either
92 Set 100Mbps (Fast Ethernet) operation.
96 option can also be used to select either
105 driver supports the following media options:
107 .Bl -tag -width full-duplex
109 Force full duplex operation
111 Force half duplex operation.
114 For more information on configuring this device, see
119 driver supports adapters and embedded controllers based on the AMD PCnet/FAST,
120 PCnet/FAST+, PCnet/FAST III, PCnet/PRO and PCnet/Home Fast Ethernet chips:

126 AMD Am79C972 PCnet-FAST+

138 .It "pcn%d: couldn't map ports/memory"
139 A fatal initialization error has occurred.
140 .It "pcn%d: couldn't map interrupt"
141 A fatal initialization error has occurred.
142 .It "pcn%d: watchdog timeout"
143 The device has stopped responding to the network, or there is a problem with
144 the network connection (e.g.\& a cable fault).
145 .It "pcn%d: no memory for rx list"
146 The driver failed to allocate an mbuf for the receiver ring.
147 .It "pcn%d: no memory for tx list"
148 The driver failed to allocate an mbuf for the transmitter ring when
149 allocating a pad buffer or collapsing an mbuf chain into a cluster.
150 .It "pcn%d: chip is in D3 power state -- setting to D0"
151 This message applies only to adapters which support power
153 Some operating systems place the controller in low power
154 mode when shutting down, and some PCI BIOSes fail to bring the chip
155 out of this state before configuring it.
156 The controller loses all of
157 its PCI configuration in the D3 state, so if the BIOS does not set
158 it back to full power mode in time, it will not be able to configure it
160 The driver tries to detect this condition and bring
161 the adapter back to the D0 (full power) state, but this may not be
162 enough to return the driver to a fully operational condition.
164 you see this message at boot time and the driver fails to attach
165 the device as a network interface, you will have to perform a
166 warm boot to have the device properly configured.
168 Note that this condition only occurs when warm booting from another
170 If you power down your system prior to booting
172 the card should be configured correctly.
