|
||||
.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 wb"
|
||||
.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_wb_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 Winbond W89C840F Fast Ethernet controller
|
||||
chip.
|
||||
The 840F should not be confused with the 940F, which is
|
||||
an NE2000 clone and only supports 10Mbps speeds.
|
||||
.Pp
|
||||
The Winbond controller uses bus master DMA and is designed to be
|
||||
a DEC 'tulip' workalike.
|
||||
It differs from the standard DEC design
|
||||
in several ways: the control and status registers are spaced 4
|
||||
bytes apart instead of 8, and the receive filter is programmed through
|
||||
registers rather than by downloading a special setup frame via
|
||||
the transmit DMA engine.
|
||||
Using an external PHY, the Winbond chip
|
||||
supports both 10 and 100Mbps speeds in either full or half duplex.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver supports the following media types:
|
||||
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
||||
.It autoselect
|
||||
Enable autoselection of the media type and options.
|
||||
This is only
|
||||
supported if the PHY chip attached to the Winbond controller
|
||||
supports NWAY autonegotiation.
|
||||
The user can manually override
|
||||
the autoselected mode by adding media options to the
|
||||
.Pa /etc/rc.conf
|
||||
file.
|
||||
.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:
|
||||
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
||||
.It full-duplex
|
||||
Force full duplex operation.
|
||||
.It half-duplex
|
||||
Force half duplex operation.
|
||||
.El
|
||||
.Pp
|
||||
Note that the 100baseTX media type is only available if supported
|
||||
by the adapter.
|
||||
For more information on configuring this device, see
|
||||
.Xr ifconfig 8 .
|
||||
.Sh HARDWARE
|
||||
The
|
||||
.Nm
|
||||
driver supports Winbond W89C840F based Fast Ethernet
|
||||
adapters and embedded controllers including:
|
||||

|
||||
.Sh DIAGNOSTICS
|
||||
.Bl -diag
|
||||
.It "wb%d: couldn't map memory"
|
||||
A fatal initialization error has occurred.
|
||||
.It "wb%d: couldn't map interrupt"
|
||||
A fatal initialization error has occurred.
|
||||
.It "wb%d: watchdog timeout"
|
||||
The device has stopped responding to the network, or there is a problem with
|
||||
the network connection (cable).
|
||||
.It "wb%d: no memory for rx list"
|
||||
The driver failed to allocate an mbuf for the receiver ring.
|
||||
.It "wb%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 "wb%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 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 AUTHORS
|
||||
The
|
||||
.Nm
|
||||
driver was written by
|
||||
.An Bill Paul Aq Mt wpaul@ctr.columbia.edu .
|
||||
.Sh BUGS
|
||||
The Winbond chip seems to behave strangely in some cases when the
|
||||
link partner switches modes.
|
||||
If for example both sides are set to
|
||||
10Mbps half-duplex, and the other end is changed to 100Mbps
|
||||
full-duplex, the Winbond's receiver suddenly starts writing trash
|
||||
all over the RX descriptors.
|
||||
The
|
||||
.Nm
|
||||
driver handles this by forcing a reset of both the controller
|
||||
chip and attached PHY.
|
||||
This is drastic, but it appears to be the
|
||||
only way to recover properly from this condition.
