    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 National Semicon-
         ductor DP83840A or other MII-compliant PHY may be attached to the Thun-
         derLAN's MII bus.  If a DP83840A or equivalent is available, the Thunder-
         LAN 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/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).

    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.
