1  Overview
===========

The sk98lin driver supports the Marvell Yukon and SysKonnect 
SK-98xx/SK-95xx compliant Gigabit Ethernet Adapter on Linux. It has 
been tested with Linux on Intel/x86 machines.
***


2  Required Files
=================

The linux kernel source.
No additional files required.
***


3  Installation
===============

It is recommended to download the latest version of the driver from the 
SysKonnect web site www.syskonnect.com. If you have downloaded the latest
driver, the Linux kernel has to be patched before the driver can be 
installed. For details on how to patch a Linux kernel, refer to the 
patch.txt file.

3.1  Driver Installation
------------------------

The following steps describe the actions that are required to install
the driver and to start it manually. These steps should be carried
out for the initial driver setup. Once confirmed to be ok, they can
be included in the system start.

NOTE 1: To perform the following tasks you need 'root' access.

NOTE 2: In case of problems, please read the section "Troubleshooting" 
        below.

The driver can either be integrated into the kernel or it can be compiled 
as a module. Select the appropriate option during the kernel 
configuration.

Compile/use the driver as a module
----------------------------------
To compile the driver, go to the directory /usr/src/linux and
execute the command "make menuconfig" or "make xconfig" and proceed as 
follows:

To integrate the driver permanently into the kernel, proceed as follows:

1. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
2. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support" 
   with (*) 
3. Build a new kernel when the configuration of the above options is 
   finished.
4. Install the new kernel.
5. Reboot your system.

To use the driver as a module, proceed as follows:

1. Enable 'loadable module support' in the kernel.
2. For automatic driver start, enable the 'Kernel module loader'.
3. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
4. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support" 
   with (M)
5. Execute the command "make modules".
6. Execute the command "make modules_install".
   The appropriate modules will be installed.
7. Reboot your system.


Load the module manually
------------------------
To load the module manually, proceed as follows:

1. Enter "modprobe sk98lin".
2. If a Marvell Yukon or SysKonnect SK-98xx adapter is installed in 
   your computer and you have a /proc file system, execute the command:
   "ls /proc/net/sk98lin/" 
   This should produce an output containing a line with the following 
   format:
   eth0   eth1  ...
   which indicates that your adapter has been found and initialized.
   
   NOTE 1: If you have more than one Marvell Yukon or SysKonnect SK-98xx 
           adapter installed, the adapters will be listed as 'eth0', 
                   'eth1', 'eth2', etc.
                   For each adapter, repeat steps 3 and 4 below.

   NOTE 2: If you have other Ethernet adapters installed, your Marvell
           Yukon or SysKonnect SK-98xx adapter will be mapped to the 
                   next available number, e.g. 'eth1'. The mapping is executed 
                   automatically.
           The module installation message (displayed either in a system
           log file or on the console) prints a line for each adapter 
           found containing the corresponding 'ethX'.

3. Select an IP address and assign it to the respective adapter by 
   entering:
   ifconfig eth0 <ip-address>
   With this command, the adapter is connected to the Ethernet. 
   
   SK-98xx Gigabit Ethernet Server Adapters: The yellow LED on the adapter 
   is now active, the link status LED of the primary port is active and 
   the link status LED of the secondary port (on dual port adapters) is 
   blinking (if the ports are connected to a switch or hub).
   SK-98xx V2.0 Gigabit Ethernet Adapters: The link status LED is active.
   In addition, you will receive a status message on the console stating
   "ethX: network connection up using port Y" and showing the selected 
   connection parameters (x stands for the ethernet device number 
   (0,1,2, etc), y stands for the port name (A or B)).

   NOTE: If you are in doubt about IP addresses, ask your network
         administrator for assistance.
  
4. Your adapter should now be fully operational.
   Use 'ping <otherstation>' to verify the connection to other computers 
   on your network.
5. To check the adapter configuration view /proc/net/sk98lin/[devicename].
   For example by executing:    
   "cat /proc/net/sk98lin/eth0" 

Unload the module
-----------------
To stop and unload the driver modules, proceed as follows:

1. Execute the command "ifconfig eth0 down".
2. Execute the command "rmmod sk98lin".

3.2  Inclusion of adapter at system start
-----------------------------------------

Since a large number of different Linux distributions are 
available, we are unable to describe a general installation procedure
for the driver module.
Because the driver is now integrated in the kernel, installation should
be easy, using the standard mechanism of your distribution.
Refer to the distribution's manual for installation of ethernet adapters.

***

4  Driver Parameters
====================

Parameters can be set at the command line after the module has been 
loaded with the command 'modprobe'.
In some distributions, the configuration tools are able to pass parameters
to the driver module.

If you use the kernel module loader, you can set driver parameters
in the file /etc/modprobe.conf (or /etc/modules.conf in 2.4 or earlier).
To set the driver parameters in this file, proceed as follows:

1. Insert a line of the form :
   options sk98lin ...
   For "...", the same syntax is required as described for the command
   line parameters of modprobe below.
2. To activate the new parameters, either reboot your computer
   or 
   unload and reload the driver.
   The syntax of the driver parameters is:

        modprobe sk98lin parameter=value1[,value2[,value3...]]

   where value1 refers to the first adapter, value2 to the second etc.

NOTE: All parameters are case sensitive. Write them exactly as shown 
      below.

Example:
Suppose you have two adapters. You want to set auto-negotiation
on the first adapter to ON and on the second adapter to OFF.
You also want to set DuplexCapabilities on the first adapter
to FULL, and on the second adapter to HALF.
Then, you must enter:

        modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half

NOTE: The number of adapters that can be configured this way is
      limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM).
      The current limit is 16. If you happen to install
      more adapters, adjust this and recompile.


4.1  Per-Port Parameters
------------------------

These settings are available for each port on the adapter.
In the following description, '?' stands for the port for
which you set the parameter (A or B).

Speed
-----
Parameter:    Speed_?
Values:       10, 100, 1000, Auto
Default:      Auto

This parameter is used to set the speed capabilities. It is only valid 
for the SK-98xx V2.0 copper adapters.
Usually, the speed is negotiated between the two ports during link 
establishment. If this fails, a port can be forced to a specific setting
with this parameter.

Auto-Negotiation
----------------
Parameter:    AutoNeg_?
Values:       On, Off, Sense
Default:      On
  
The "Sense"-mode automatically detects whether the link partner supports
auto-negotiation or not.

Duplex Capabilities
-------------------
Parameter:    DupCap_?
Values:       Half, Full, Both
Default:      Both

This parameters is only relevant if auto-negotiation for this port is 
not set to "Sense". If auto-negotiation is set to "On", all three values
are possible. If it is set to "Off", only "Full" and "Half" are allowed.
This parameter is useful if your link partner does not support all
possible combinations.

Flow Control
------------
Parameter:    FlowCtrl_?
Values:       Sym, SymOrRem, LocSend, None
Default:      SymOrRem

This parameter can be used to set the flow control capabilities the 
port reports during auto-negotiation. It can be set for each port 
individually.
Possible modes:
   -- Sym      = Symmetric: both link partners are allowed to send 
                  PAUSE frames
   -- SymOrRem = SymmetricOrRemote: both or only remote partner 
                  are allowed to send PAUSE frames
   -- LocSend  = LocalSend: only local link partner is allowed 
                  to send PAUSE frames
   -- None     = no link partner is allowed to send PAUSE frames
  
NOTE: This parameter is ignored if auto-negotiation is set to "Off".

Role in Master-Slave-Negotiation (1000Base-T only)
--------------------------------------------------
Parameter:    Role_?
Values:       Auto, Master, Slave
Default:      Auto

This parameter is only valid for the SK-9821 and SK-9822 adapters.
For two 1000Base-T ports to communicate, one must take the role of the
master (providing timing information), while the other must be the 
slave. Usually, this is negotiated between the two ports during link 
establishment. If this fails, a port can be forced to a specific setting
with this parameter.
