-.Sh NAME
-.Nm wb
-.Nd "Winbond W89C840F 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 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:
-.Pp
-.Bl -bullet -compact
-.It
-Trendware TE100-PCIE
-.El
-.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.
-.El
-.Sh SEE ALSO
-.Xr arp 4 ,
-.Xr miibus 4 ,
-.Xr netintro 4 ,
-.Xr ng_ether 4 ,
-.Xr ifconfig 8
-.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.

-/*
- * The Winbond W89C840F chip is a bus master; in some ways it resembles
- * a DEC 'tulip' chip, only not as complicated. Unfortunately, it has
- * one major difference which is that while the registers do many of
- * the same things as a tulip adapter, the offsets are different: where
- * tulip registers are typically spaced 8 bytes apart, the Winbond
- * registers are spaced 4 bytes apart. The receiver filter is also
- * programmed differently.
- *
- * Like the tulip, the Winbond chip uses small descriptors containing
- * a status word, a control word and 32-bit areas that can either be used
- * to point to two external data blocks, or to point to a single block
- * and another descriptor in a linked list. Descriptors can be grouped
- * together in blocks to form fixed length rings or can be chained
- * together in linked lists. A single packet may be spread out over
- * several descriptors if necessary.
- *
- * For the receive ring, this driver uses a linked list of descriptors,
- * each pointing to a single mbuf cluster buffer, which us large enough
- * to hold an entire packet. The link list is looped back to created a
- * closed ring.
- *
- * For transmission, the driver creates a linked list of 'super descriptors'
- * which each contain several individual descriptors linked toghether.
- * Each 'super descriptor' contains WB_MAXFRAGS descriptors, which we
- * abuse as fragment pointers. This allows us to use a buffer managment
- * scheme very similar to that used in the ThunderLAN and Etherlink XL
- * drivers.
- *
- * Autonegotiation is performed using the external PHY via the MII bus.
- * The sample boards I have all use a Davicom PHY.
- *
- * Note: the author of the Linux driver for the Winbond chip alludes
- * to some sort of flaw in the chip's design that seems to mandate some
- * drastic workaround which signigicantly impairs transmit performance.
- * I have no idea what he's on about: transmit performance with all
- * three of my test boards seems fine.

- * A transmit 'super descriptor' is actually WB_MAXFRAGS regular

- * The advantage to using this scheme is that it avoids buffer copies.
- * The disadvantage is that there's a certain amount of overhead due
- * to the fact that each 'fragment' is 16 bytes long. In my tests,
- * this limits top speed to about 10.5MB/sec. It should be more like
- * 11.5MB/sec. However, the upshot is that you can achieve better
- * results on slower machines: a Pentium 200 can pump out packets at
