tl - Texas Instruments ThunderLAN Ethernet driver
tl* at pci? dev ? function ?
The tl driver provides support for PCI Ethernet adapters
based on the
Texas Instruments ThunderLAN Ethernet controller chip. This
large number of Compaq PCI-bus Ethernet adapters as well as
Ethernet controllers built in to several models of Compaq
servers and Compaq Deskpro desktop machines. This driver

The ThunderLAN controller has a standard MII interface that
to 32 physical interface devices (PHYs). It also has a
PHY hardwired at MII address 31, which may be used in some
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,
chip can operate at either 100Mbps or 10Mbps in either
full-duplex modes. The ThunderLAN's built-in PHY and the
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

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

The tl device driver first appeared in FreeBSD 2.2. OpenBSD
first appeared in OpenBSD 2.4.
