    Caveats:
    
    I am not sure if 100BaseTX daughterboards (for those cards which
    support such things) will work.  I haven't had any solid evidence
    either way.

    However, if a card supports 100BaseTx without requiring an add
    on daughterboard, it should work with 100BaseTx.

    The "Netelligent 10 T/2 PCI UTP/Coax" (b012) device is untested,
    but I do not expect any problems.
    

II.   Driver Options
        1. You can append debug=x to the end of the insmod line to get
           debug messages, where x is a bit field where the bits mean
           the following:
           
           0x01         Turn on general debugging messages.
           0x02         Turn on receive debugging messages.
           0x04         Turn on transmit debugging messages.
           0x08         Turn on list debugging messages.

        2. You can append aui=1 to the end of the insmod line to cause
           the adapter to use the AUI interface instead of the 10 Base T
           interface.  This is also what to do if you want to use the BNC
           connector on a TLAN based device.  (Setting this option on a
           device that does not have an AUI/BNC connector will probably
           cause it to not function correctly.)

        3. You can set duplex=1 to force half duplex, and duplex=2 to
           force full duplex.

        4. You can set speed=10 to force 10Mbs operation, and speed=100
           to force 100Mbs operation. (I'm not sure what will happen
           if a card which only supports 10Mbs is forced into 100Mbs
           mode.)

        5. You have to use speed=X duplex=Y together now. If you just
           do "insmod tlan.o speed=100" the driver will do Auto-Neg.
           To force a 10Mbps Half-Duplex link do "insmod tlan.o speed=10 
           duplex=1".

        6. If the driver is built into the kernel, you can use the 3rd
           and 4th parameters to set aui and debug respectively.  For
           example:

           ether=0,0,0x1,0x7,eth0

           This sets aui to 0x1 and debug to 0x7, assuming eth0 is a
           supported TLAN device.

           The bits in the third byte are assigned as follows:

                0x01 = aui
                0x02 = use half duplex
                0x04 = use full duplex
                0x08 = use 10BaseT
                0x10 = use 100BaseTx

           You also need to set both speed and duplex settings when forcing
           speeds with kernel-parameters. 
           ether=0,0,0x12,0,eth0 will force link to 100Mbps Half-Duplex.

        7. If you have more than one tlan adapter in your system, you can
           use the above options on a per adapter basis. To force a 100Mbit/HD
           link with your eth1 adapter use:
           
           insmod tlan speed=0,100 duplex=0,1

           Now eth0 will use auto-neg and eth1 will be forced to 100Mbit/HD.
           Note that the tlan driver supports a maximum of 8 adapters.


III.  Things to try if you have problems.
        1. Make sure your card's PCI id is among those listed in
           section I, above.
        2. Make sure routing is correct.
        3. Try forcing different speed/duplex settings
