PCI fast ethernet adapters, plus man pages.
if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
various other PNIC devices
if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
other boards based on the Macronix 98713, 98713A, 98715, 98715A
and 98725 chips
if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
Rhine II chips (note: the D-Link and certain other cards
that actually use a Rhine II chip still return the PCI
device ID of the Rhine I. I don't know why, and it doesn't
really matter since the driver treats both chips the same
anyway.)
if_wb.c: Trendware TE100-PCIE and various other cards based on the
Winbond W89C840F chip (the Trendware card is identical to
the sample boards Winbond sent me, so who knows how many
clones there are running around)
All drivers include support for ifmedia, BPF and hardware multicast
filtering.
Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.
I also have a driver for the ASIX AX88140A in the works.

Lite-On 82c168/82c169 PNIC fast ethernet device driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device pn0"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for PCI ethernet adapters and embedded
|
|
controllers based on the Lite-On 82c168 and 82c169 fast ethernet
|
|
controller chips. This includes the LinkSys LNE100TX, the
|
|
Bay Networks Netgear FA310TX revision D1, the Matrox Networks
|
|
FastNIC 10/100, certain adapters manufactured by D-Link and
|
|
Trendware, and various other commodity fast ethernet cards.
|
|
.Pp
|
|
The Lite-On chips use bus master DMA and are designed to be
|
|
DEC 'tulip' workalikes. Many vendors that formerly based their
|
|
designs around the DEC 21x4x devices are now using the PNIC
|
|
instead. The chips support both an internal transceiver
|
|
and external transceivers via an MII bus. The Lite-On parts are
|
|
advertised as being register compatible with the DEC 21x4x
|
|
controllers, however there are some differences in the way the
|
|
EEPROM and MII access is done. The PNIC controllers support both
|
|
10 and 100Mbps speeds in either full or half duplex.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to the
|
|
.Pa /etc/rc.conf
|
|
fine.
|
|
.It 10baseT/UTP
|
|
Set 10Mbps operation. The
|
|
.Ar mediaopt
|
|
option can also be used to select either
|
|
.Ar full-duplex
|
|
or
|
|
.Ar half-duplex modes.
|
|
.It 100baseTX
|
|
Set 100Mbps (fast ethernet) operation. The
|
|
.Ar mediaopt
|
|
option can also be used to select either
|
|
.Ar full-duplex
|
|
or
|
|
.Ar half-duplex
|
|
modes.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It full-duplex
|
|
Force full duplex operation
|
|
.It half-duplex
|
|
Force half duplex operation.
|
|
.El
|
|

|
|
Note that the 100baseTX media type is only available if supported
|
|
by the adapter.

For more information on configuring this device, see

|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "pn%d: couldn't map memory"
|
|
A fatal initialization error has occurred.
|
|
.It "pn%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "pn%d: watchdog timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
|
|
.It "pn%d: no memory for rx list"
|
|
The driver failed to allocate an mbuf for the receiver ring.
|
|
.It "pn%d: no memory for tx list"
|
|
The driver fauled to allocate an mbuf for the transmitter ring when
|
|
allocating a pad buffer or collapsing an mbuf chain into a cluster.
|
|
.It "pn%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 won't 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 second
|
|
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.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 3.0 .
|
|
.Sh AUTHOR
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Bill Paul Aq wpaul@ctr.columbia.edu .
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
driver currently only supports cards with external transceivers
|
|
connected to the PNIC controller via its MII bus. This is because
|
|
the author had no boards available for testing which made use of the
|
|
internal transceiver. Most of the PNIC implementations on the market
|
|
today use an external PHY, so hopefully this will not present any
|
|
serious problems. Code to support the internal transceiver may be
|
|
added later if hardware becomes available.
