To compile this driver into the kernel,
place the following lines in your
kernel configuration file:

Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_tl_load="YES"
DESCRIPTION
The
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
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
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/UTP
Set 10Mbps operation
100baseTX
Set 100Mbps (Fast Ethernet) operation
10base5/AUI
Enable AUI/BNC interface (useful only with the built-in PHY).
The
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).

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 collapsing an mbuf chain into a cluster.
