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
