TLAN driver for Linux, version 1.0
README

Well, I'm back.  The TLAN driver seems pretty stable, so I'm
declaring this cycle of development finished, and calling the
driver 1.0.  I will, of course continue to work on improving
the driver, and work towards a 2.0 release.



I.  Supported Devices.

    Only PCI devices will work with this driver.

    Supported:
    Vendor ID   Device ID       Name
    0e11        ae32            Compaq Netelligent 10/100 TX PCI UTP
    0e11        ae34            Compaq Netelligent 10 T PCI UTP
    0e11        ae35            Compaq Integrated NetFlex 3/P
    0e11        ae40            Compaq Netelligent Dual 10/100 TX PCI UTP
    0e11        ae43            Compaq Netelligent Integrated 10/100 TX UTP
    0e11        b011            Compaq Netelligent 10/100 TX Embedded UTP
    0e11        b012            Compaq Netelligent 10 T/2 PCI UTP/Coax
    0e11        b030            Compaq Netelligent 10/100 TX UTP
    0e11        f130            Compaq NetFlex 3/P
    0e11        f150            Compaq NetFlex 3/P
    108d        0012            Olicom OC-2325  
    108d        0013            Olicom OC-2183
    108d        0014            Olicom OC-2326  


    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.  Building the Driver.

    The TLAN driver may be compiled into the kernel, or it may be compiled
    as a module separately, or in the kernel.  A patch is included for
    2.0.29 (which also works for 2.0.30, 2.0.31, and 2.0.32).

    To compile it as part of the kernel:
        1. Download and untar the TLAN driver package.
        2. If your kernel is 2.1.45 or later, you do not need to patch the
           kernel sources.  Copy the tlan.c and tlan.h to drivers/net in
           the kernel source tree.
        3. Otherwise, apply the appropriate patch for your kernel.  For
           example:

               cd /usr/src/linux
               patch -p1 < kernel.2.0.29

        4. Copy the files tlan.c and tlan.h from the TLAN package to the
           directory drivers/net in the Linux kernel source tree.
        5. Configure your kernel for the TLAN driver.  Answer 'Y' when
           prompted to ask about experimental code (the first question).
           Then answer 'Y' when prompted if to include TI ThunderLAN
           support.  If you want the driver compiled as a module, answer 'M'
           instead of 'Y'.
        6. Make the kernel and, if necessary, the modules.
    
    To compile the TLAN driver independently:
        1. Download and untar the TLAN driver package.
        2. Change to the tlan directory.
        3. If you are NOT using a versioned kernel (ie, want an non-
           versioned module), edit the Makefile, and comment out the
           line:
                 MODVERSIONS = -DMODVERSIONS
        4. Run 'make'.


III.  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 messsages.

        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.)

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

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

        3. 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 SA_INTERRUPT flag when reserving the irq.
                0x04 = use half duplex
                0x08 = use full duplex
                0x10 = use 10BaseT
                0x20 = use 100BaseTx


IV.  Things to try if you have problems.
        1. Make sure your card's PCI id is among those listed in
           section I, above.
        1. Make sure routing is correct.
        2. If you are using a 2.1.x kernel, try to duplicate the
           problem on a 2.0.x (preferably 2.0.29 or 2.0.30) kernel.
