The
tl driver provides support for PCI Ethernet
adapters based on the Texas Instruments ThunderLAN Ethernet controller chip.
This includes a large number of Compaq PCI-bus Ethernet adapters as well as
the integrated Ethernet controllers built in to several models of Compaq
Prosignia servers and Compaq Deskpro desktop machines. This driver also
supports the Olicom OC-2135/2138, OC-2325 and OC-2326 10/100 TX UTP adapters
and the Racore 8165 10/100baseTX and 8148 10baseT/100baseTX/100baseFX
multi-personality cards.
The ThunderLAN controller has a standard MII interface that supports up to 32
physical interface devices (PHYs). It also has a built-in 10baseT PHY
hardwired at MII address 31, which may be used in some 10Mbps-only hardware
configurations. In 100Mbps configurations, a National Semiconductor DP83840A
or other MII-compliant PHY may be attached to the ThunderLAN's MII bus. If a
DP83840A or equivalent is available, the ThunderLAN chip can operate at either
100Mbps or 10Mbps in either half-duplex or full-duplex modes. The ThunderLAN's
built-in PHY and the DP83840A also support autonegotiation.
The
tl driver supports the following media types:
-
-
- autoselect
- Enable autoselection of the media type and options. Note
that this option is only available on those PHYs that support
autonegotiation. Also, the PHY will not advertise those modes that have
been explicitly disabled using the following media options.
-
-
- 10baseT
- Set 10Mbps operation.
-
-
- 100baseTX
- Set 100Mbps (Fast Ethernet) operation.
-
-
- 10base5
- Enable AUI/BNC interface (useful only with the built-in
PHY).
The
tl driver supports the following media options:
-
-
- full-duplex
- Force full duplex operation.
-
-
- half-duplex
- Force half duplex operation.
-
-
- hw-loopback
- Enable hardware loopback mode.
Note that the 100baseTX media type is only available if supported by the PHY.
For more information on configuring this device, see
ifconfig(8).
- tl0: couldn't map memory
- A fatal initialization error has occurred.
- tl0: couldn't map interrupt
- A fatal initialization error has occurred.
- tl0: device timeout
- The device has stopped responding to the network, or there
is a problem with the network connection (cable).
- tl0: no memory for rx list
- The driver failed to allocate an mbuf for the receiver
ring.
- tl0: 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.
