I. Supported Devices¶
Only PCI devices will work with this driver.
Compaq Netelligent 10/100 TX PCI UTP
Compaq Netelligent 10 T PCI UTP
Compaq Integrated NetFlex 3/P
Compaq Netelligent Dual 10/100 TX PCI UTP
Compaq Netelligent Integrated 10/100 TX UTP
Compaq Netelligent 10/100 TX Embedded UTP
Compaq Netelligent 10 T/2 PCI UTP/Coax
Compaq Netelligent 10/100 TX UTP
Compaq NetFlex 3/P
Compaq NetFlex 3/P
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¶
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:
Turn on general debugging messages.
Turn on receive debugging messages.
Turn on transmit debugging messages.
Turn on list debugging messages.
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.)
You can set duplex=1 to force half duplex, and duplex=2 to force full duplex.
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.)
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”.
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:
use half duplex
use full duplex
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.
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¶
Make sure your card’s PCI id is among those listed in section I, above.
Make sure routing is correct.
Try forcing different speed/duplex settings
