SYNOPSIS

device miibus device wb

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

if_wb_load="YES"

DESCRIPTION

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.

The driver supports the following media types:

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 /etc/rc.conf file.

10baseT/UTP

Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX

Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

The driver supports the following media options:

full-duplex

Force full duplex operation.

half-duplex

Force half duplex operation.

Note that the 100baseTX media type is only available if supported by the adapter. For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

"wb%d: couldn't map memory"

A fatal initialization error has occurred.

"wb%d: couldn't map interrupt"

A fatal initialization error has occurred.

"wb%d: watchdog timeout"

The device has stopped responding to the network, or there is a problem with the network connection (cable).

"wb%d: no memory for rx list"

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

"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.

"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.

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.
