-.Sh NAME

-.Nm pcn

-.Nd "AMD PCnet/PCI Fast Ethernet device driver"

-.Sh SYNOPSIS

-To compile this driver into the kernel,

-place the following lines in your

-kernel configuration file:

-.Bd -ragged -offset indent

-.Cd "device miibus"

-.Cd "device pcn"

-.Ed

-.Pp

-Alternatively, to load the driver as a

-module at boot time, place the following line in

-.Xr loader.conf 5 :

-.Bd -literal -offset indent

-if_pcn_load="YES"

-.Ed

-.Sh DEPRECATION NOTICE

-The

-.Nm

-driver is not present in

-.Fx 13.0

-and later.

-See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more

-information.

-.Sh DESCRIPTION

-The

-.Nm

-driver provides support for PCI Ethernet adapters and embedded

-controllers based on the AMD PCnet/FAST, PCnet/FAST+, PCnet/FAST III,

-PCnet/PRO and PCnet/Home Ethernet controller chips.

-Supported NIC's include the Allied Telesyn AT-2700 family.

-.Pp

-The PCnet/PCI chips include a 100Mbps Ethernet MAC and support

-both a serial and MII-compliant transceiver interface.

-They use a bus master DMA and a scatter/gather descriptor scheme.

-The AMD chips provide a mechanism for zero-copy receive,

-providing good performance in server environments.

-Receive address filtering is provided using a single perfect filter entry

-for the station address and a 64-bit multicast hash table.

-.Pp

-The

-.Nm

-driver supports the following media types:

-.Bl -tag -width 10baseTXUTP

-.It autoselect

-Enable autoselection of the media type and options.

-The user can manually override

-the autoselected mode by adding media options to

-.Xr rc.conf 5 .

-.It 10baseT/UTP

-Set 10Mbps operation.

-The

-.Xr ifconfig 8

-.Cm mediaopt

-option can also be used to select either

-.Sq full-duplex

-or

-.Sq half-duplex

-modes.

-.It 100baseTX

-Set 100Mbps (Fast Ethernet) operation.

-The

-.Xr ifconfig 8

-.Cm mediaopt

-option can also be used to select either

-.Sq full-duplex

-or

-.Sq half-duplex

-modes.

-.El

-.Pp

-The

-.Nm

-driver supports the following media options:

-.Bl -tag -width full-duplex

-.It full-duplex

-Force full duplex operation.

-.It half-duplex

-Force half duplex operation.

-.El

-.Pp

-For more information on configuring this device, see

-.Xr ifconfig 8 .

-.Sh HARDWARE

-The

-.Nm

-driver supports adapters and embedded controllers based on the AMD PCnet/FAST,

-PCnet/FAST+, PCnet/FAST III, PCnet/PRO and PCnet/Home Fast Ethernet chips:

-.Sh DIAGNOSTICS

-.Bl -diag

-.It "pcn%d: couldn't map ports/memory"

-A fatal initialization error has occurred.

-.It "pcn%d: couldn't map interrupt"

-A fatal initialization error has occurred.

-.It "pcn%d: watchdog timeout"

-The device has stopped responding to the network, or there is a problem with

-the network connection (e.g.\& a cable fault).

-.It "pcn%d: no memory for rx list"

-The driver failed to allocate an mbuf for the receiver ring.

-.It "pcn%d: no memory for tx list"

-The driver failed to allocate an mbuf for the transmitter ring when

-allocating a pad buffer or collapsing an mbuf chain into a cluster.

-.It "pcn%d: chip is in D3 power state -- setting to D0"

-This message applies only to adapters which support power

-management.

-Some operating systems place the controller in low power

-mode when shutting down, and some PCI BIOSes fail to bring the chip

-out of this state before configuring it.

-The controller loses all of

-its PCI configuration in the D3 state, so if the BIOS does not set

-it back to full power mode in time, it will not be able to configure it

-correctly.

-The driver tries to detect this condition and bring

-the adapter back to the D0 (full power) state, but this may not be

-enough to return the driver to a fully operational condition.

-If

-you see this message at boot time and the driver fails to attach

-the device as a network interface, you will have to perform a

-warm boot to have the device properly configured.

-.Pp

-Note that this condition only occurs when warm booting from another

-operating system.

-If you power down your system prior to booting

-.Fx ,

-the card should be configured correctly.
