WB 4 -.Os -.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. diff --git a/sys/amd64/conf/GENERIC b/sys/amd64/conf/GENERIC index a93fd4242762..520f64734bb9 100644 --- a/sys/amd64/conf/GENERIC +++ b/sys/amd64/conf/GENERIC @@ -278,7 +278,6 @@

Descriptors can be grouped - * together in blocks to form fixed length rings or can be chained - * together in linked lists.
