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
55 .Sh DEPRECATION NOTICE
58 driver is not present in
61 See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more
66 driver provides support for PCI Ethernet adapters and embedded
67 controllers based on the AMD PCnet/FAST, PCnet/FAST+, PCnet/FAST III,
68 PCnet/PRO and PCnet/Home Ethernet controller chips.
69 Supported NIC's include the Allied Telesyn AT-2700 family.
71 The PCnet/PCI chips include a 100Mbps Ethernet MAC and support
72 both a serial and MII-compliant transceiver interface.
73 They use a bus master DMA and a scatter/gather descriptor scheme.
74 The AMD chips provide a mechanism for zero-copy receive,
75 providing good performance in server environments.
76 Receive address filtering is provided using a single perfect filter entry
77 for the station address and a 64-bit multicast hash table.
81 driver supports the following media types:
82 .Bl -tag -width 10baseTXUTP
84 Enable autoselection of the media type and options.
85 The user can manually override
86 the autoselected mode by adding media options to
93 option can also be used to select either
99 Set 100Mbps (Fast Ethernet) operation.
103 option can also be used to select either
112 driver supports the following media options:
113 .Bl -tag -width full-duplex
115 Force full duplex operation.
117 Force half duplex operation.

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