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:

    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.
