     tl - Texas Instruments ThunderLAN Ethernet device driver

     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):


     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 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

     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 supported by the
     PHY.  For more information on configuring this device, see ifconfig(8).

     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:

        Olicom OC-2135/2138 10/100 TX UTP adapter
        Olicom OC-2325/OC-2326 10/100 TX UTP adapter
        Racore 8148 10baseT/100baseTX/100baseFX adapter
        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:

        Compaq Netelligent 10
        Compaq Netelligent 10 T PCI UTP/Coax
        Compaq Netelligent 10/100
        Compaq Netelligent 10/100 Dual-Port
        Compaq Netelligent 10/100 Proliant
        Compaq Netelligent 10/100 TX Embedded UTP
        Compaq Netelligent 10/100 TX UTP
        Compaq NetFlex 3P
        Compaq NetFlex 3P Integrated
        Compaq NetFlex 3P w/BNC

     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.

     The tl device driver first appeared in FreeBSD 2.2.

     The tl driver was written by Bill Paul <[email protected]>.
