NAME
tl - Texas Instruments ThunderLAN Ethernet device driver
SYNOPSIS
To compile this driver into the kernel, place the following
lines in your
kernel configuration file:
device miibus
device tl
Alternatively, to load the driver as a module at boot time,
place the
following line in loader.conf(5):
if_tl_load="YES"
DESCRIPTION
- The tl driver provides support for PCI Ethernet adapters
- based on the
Texas Instruments ThunderLAN Ethernet controller chip. - 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 Na - tional 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 avail
- able on those
PHYs that support autonegotiation. - Also, the PHY
will not advertise those modes that - have been
explicitly disabled using the follow - ing media
options. - 10baseT/UTP Set 10Mbps operation
- 100baseTX Set 100Mbps (Fast Ethernet) operation
- 10base5/AUI 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 sup
- ported by the
PHY. For more information on configuring this device, see - ifconfig(8).
HARDWARE
- The tl driver supports Texas Instruments ThunderLAN based
- Ethernet and
Fast Ethernet adapters including a large number of Compaq - PCI Ethernet
adapters. Also supported are: - +o Olicom OC-2135/2138 10/100 TX UTP adapter

+o Racore 8148 10baseT/100baseTX/100baseFX adapter
+o Racore 8165 10/100baseTX adapter - The tl driver also supports the built-in Ethernet adapters
- of various
Compaq Prosignia servers and Compaq Deskpro desktop machines - including:
- +o Compaq Netelligent 10
+o Compaq Netelligent 10 T PCI UTP/Coax
+o Compaq Netelligent 10/100
+o Compaq Netelligent 10/100 Dual-Port
+o Compaq Netelligent 10/100 Proliant
+o Compaq Netelligent 10/100 TX Embedded UTP
+o Compaq Netelligent 10/100 TX UTP
+o Compaq NetFlex 3P
+o Compaq NetFlex 3P Integrated
+o Compaq NetFlex 3P w/BNC
DIAGNOSTICS
- tl%d: couldn't map memory A fatal initialization error has
- occurred.
- tl%d: couldn't map interrupt A fatal initialization error
- has occurred.
- tl%d: device timeout The device has stopped responding to
- the network,
or there is a problem with the network connection (cable). - tl%d: no memory for rx list The driver failed to allocate
- an mbuf for
the receiver ring. - tl%d: no memory for tx list The driver failed to allocate
- an mbuf for
the transmitter ring when allocating a pad buffer or col - lapsing an mbuf
chain into a cluster.
