-** Introduction

-This document describes what I managed to discover about the protocol used to

-specify force effects to I-Force 2.0 devices.  None of this information comes

-from Immerse. That's why you should not trust what is written in this

-document. This document is intended to help understanding the protocol.

-This is not a reference. Comments and corrections are welcome.  To contact me,

-send an email to: deneux@ifrance.com

-

-** WARNING **

-I may not be held responsible for any dammage or harm caused if you try to

-send data to your I-Force device based on what you read in this document.

-

-** Preliminary Notes:

-All values are hexadecimal with big-endian encoding (msb on the left). Beware,

-values inside packets are encoded using little-endian.  Bytes whose roles are

-unknown are marked ???  Information that needs deeper inspection is marked (?)

-

-** General form of a packet **

-This is how packets look when the device uses the rs232 to communicate.

-2B OP LEN DATA CS

-CS is the checksum. It is equal to the exclusive or of all bytes.

-

-When using USB:

-OP DATA

-The 2B, LEN and CS fields have disappeared, probably because USB handles frames and

-data corruption is handled or unsignificant.

-

-First, I describe effects that are sent by the device to the computer

-

-** Device input state

-This packet is used to indicate the state of each button and the value of each

-axis

-OP= 01 for a joystick, 03 for a wheel

-LEN= Varies from device to device

-00 X-Axis lsb

-01 X-Axis msb

-02 Y-Axis lsb, or gas pedal for a wheel

-03 Y-Axis msb, or brake pedal for a wheel

-04 Throttle

-05 Buttons

-06 Lower 4 bits: Buttons

-   Upper 4 bits: Hat

-07 Rudder

-

-** Device effects states

-OP= 02

-LEN= Varies

-00 ? Bit 1 (Value 2) is the value of the deadman switch

-01 Bit 8 is set if the effect is playing. Bits 0 to 7 are the effect id.

-02 ??

-03 Address of parameter block changed (lsb)

-04 Address of parameter block changed (msb)

-05 Address of second parameter block changed (lsb)

-... depending on the number of parameter blocks updated

-

-** Force effect **

-OP=  01

-LEN= 0e

-00 Channel (when playing several effects at the same time, each must be assigned a channel)

-01 Wave form

-        Val 00 Constant

-        Val 20 Square

-        Val 21 Triangle

-        Val 22 Sine

-        Val 41 Friction (Force = f(velocity)) and Inertia (Force = f(acceleration))

-

-        

-02 Axes affected and trigger

-        Bits 4-7: Val 2 = effect along one axis. Byte 05 indicates direction

-                  Val 4 = X axis only. Byte 05 must contain 5a

-                  Val 8 = Y axis only. Byte 05 must contain b4

-                  Val c = X and Y axes. Bytes 05 must contain 60

-        Bits 0-3: Val 0 = No trigger

-                  Val x+1 = Button x triggers the effect

-        When the whole byte is 0, cancel the previously set trigger

-

-03-04 Duration of effect (little endian encoding, in ms)

-

-05 Direction of effect, if applicable. Else, see 02 for value to assign.

-

-06-07 Minimum time between triggering.

-

-08-09 Address of periodicity or magnitude parameters

-0a-0b Address of attack and fade parameters, or ffff if none.

-*or*

-08-09 Address of interactive parameters for X-axis, or ffff if not applicable

-0a-0b Address of interactive parameters for Y-axis, or ffff if not applicable

-

-** Time based parameters **

-

-*** Attack and fade ***

-OP=  02

-00-01 Address where to store the parameteres

-02-03 Duration of attack (little endian encoding, in ms)

-08 Positive saturation (Val 0a = 1000 (decimal) Val 64 = 10000 (decimal))

-09 Negative saturation

-

-The encoding is a bit funny here: For coeffs, these are signed values. The

-maximum value is 64 (100 decimal), the min is 9c.

-For the offset, the minimum value is FE0C, the maximum value is 01F4.

-For the deadband, the minimum value is 0, the max is 03E8.

-** Controls **

-OP=  41

-LEN= 03

-00 Channel

-01 Start/Stop

-        Val 00: Stop

-        Val 01: Start and play once.

-        Val 41: Start and play n times (See byte 02 below)

-02 Number of iterations n.

-

-** Init **

-

-*** Querying features ***

-OP=  ff

-Query command. Length varies according to the query type.

-The general format of this packet is:

-ff 01 QUERY [INDEX] CHECKSUM

-reponses are of the same form:

-FF LEN QUERY VALUE_QUERIED CHECKSUM2

-where LEN = 1 + length(VALUE_QUERIED)

-

-**** Query ram size ****

-QUERY = 42 ('B'uffer size)

-The device should reply with the same packet plus two additionnal bytes

-containing the size of the memory:

-ff 03 42 03 e8 CS would mean that the device has 1000 bytes of ram available.

-

-**** Query number of effects ****

-QUERY = 4e ('N'umber of effects)

-The device should respond by sending the number of effects that can be played

-at the same time (one byte)

-ff 02 4e 14 CS would stand for 20 effects.

-

-**** Vendor's id ****

-QUERY = 4d ('M'anufacturer)

-Query the vendors'id (2 bytes)

-

-**** Product id *****

-QUERY = 50 ('P'roduct)

-Query the product id (2 bytes)

-

-**** Open device ****

-QUERY = 4f ('O'pen) 

-No data returned.

-

-**** Close device *****

-QUERY = 43 ('C')lose

-No data returned.

-

-**** Query effect ****

-QUERY = 45 ('E') 

-Send effect type.

-Returns nonzero if supported (2 bytes)

-

-**** Firmware Version ****

-QUERY = 56 ('V'ersion)

-Sends back 3 bytes - major, minor, subminor

-

-*** Initialisation of the device ***

-

-**** Set Control ****

-!!! Device dependent, can be different on different models !!!

-OP=  40 <idx> <val> [<val>]

-LEN= 2 or 3

-   Idx 04 Enable or disable the spring (0/1)

-   Idx 05 Set axis saturation threshold (0..2048)

-**** Set Effect State ****

-OP=  42 <val>

-LEN= 1

-00 State

-   Bit 3 Pause force feedback

-   Bit 2 Enable force feedback

-   Bit 0 Stop all effects

-

-**** Set overall gain ****

-OP=  43 <val>

-LEN= 1

-00 Gain

-   Val 00 = 0%

-   Val 40 = 50%

-   Val 80 = 100%

-

-** Parameter memory **

-

-Each device has a certain amount of memory to store parameters of effects.

-The amount of RAM may vary, I encountered values from 200 to 1000 bytes. Below

-is the amount of memory apparently needed for every set of parameters:

- - period : 0c

- - magnitude : 02

- - attack and fade : 0e

- - interactive : 08

-

-** Appendix: How to study the protocol ? **

-

-1. Generate effects using the force editor provided with the DirectX SDK, or use Immersion Studio (freely available at their web site in the developer section: www.immersion.com)

-2. Start a soft spying RS232 or USB (depending on where you connected your joystick/wheel). I used ComPortSpy from fCoder (alpha version!)

-3. Play the effect, and watch what happens on the spy screen.

-

-A few words about ComPortSpy:

-At first glance, this soft seems, hum, well... buggy. In fact, data appear with a few seconds latency. Personnaly, I restart it every time I play an effect.

-Remember it's free (as in free beer) and alpha!

+===========================================================================
+
+
+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.
+
+
+4.2  Adapter Parameters
+-----------------------
+
+Connection Type (SK-98xx V2.0 copper adapters only)
+---------------
+Parameter:    ConType
+Values:       Auto, 100FD, 100HD, 10FD, 10HD
+Default:      Auto
+
+The parameter 'ConType' is a combination of all five per-port parameters
+within one single parameter. This simplifies the configuration of both ports
+of an adapter card! The different values of this variable reflect the most 
+meaningful combinations of port parameters.
+
+The following table shows the values of 'ConType' and the corresponding
+combinations of the per-port parameters:
+
+    ConType   |  DupCap   AutoNeg   FlowCtrl   Role             Speed
+    ----------+------------------------------------------------------
+    Auto      |  Both     On        SymOrRem   Auto             Auto
+    100FD     |  Full     Off       None       Auto (ignored)   100
+    100HD     |  Half     Off       None       Auto (ignored)   100
+    10FD      |  Full     Off       None       Auto (ignored)   10
+    10HD      |  Half     Off       None       Auto (ignored)   10
+
+Stating any other port parameter together with this 'ConType' variable
+will result in a merged configuration of those settings. This due to 
+the fact, that the per-port parameters (e.g. Speed_? ) have a higher
+priority than the combined variable 'ConType'.
+
+NOTE: This parameter is always used on both ports of the adapter card.
+
+Interrupt Moderation
+--------------------
+Parameter:    Moderation
+Values:       None, Static, Dynamic
+Default:      None
+
+Interrupt moderation is employed to limit the maximum number of interrupts
+the driver has to serve. That is, one or more interrupts (which indicate any
+transmit or receive packet to be processed) are queued until the driver 
+processes them. When queued interrupts are to be served, is determined by the
+'IntsPerSec' parameter, which is explained later below.
+
+Possible modes:
+
+   -- None - No interrupt moderation is applied on the adapter card. 
+      Therefore, each transmit or receive interrupt is served immediately
+      as soon as it appears on the interrupt line of the adapter card.
+
+   -- Static - Interrupt moderation is applied on the adapter card. 
+      All transmit and receive interrupts are queued until a complete
+      moderation interval ends. If such a moderation interval ends, all
+      queued interrupts are processed in one big bunch without any delay.
+      The term 'static' reflects the fact, that interrupt moderation is
+      always enabled, regardless how much network load is currently 
+      passing via a particular interface. In addition, the duration of
+      the moderation interval has a fixed length that never changes while
+      the driver is operational.
+
+   -- Dynamic - Interrupt moderation might be applied on the adapter card,
+      depending on the load of the system. If the driver detects that the
+      system load is too high, the driver tries to shield the system against 
+      too much network load by enabling interrupt moderation. If - at a later
+      time - the CPU utilization decreases again (or if the network load is 
+      negligible) the interrupt moderation will automatically be disabled.
+
+Interrupt moderation should be used when the driver has to handle one or more
+interfaces with a high network load, which - as a consequence - leads also to a
+high CPU utilization. When moderation is applied in such high network load 
+situations, CPU load might be reduced by 20-30%.
+
+NOTE: The drawback of using interrupt moderation is an increase of the round-
+trip-time (RTT), due to the queueing and serving of interrupts at dedicated
+moderation times.
+
+Interrupts per second
+---------------------
+Parameter:    IntsPerSec
+Values:       30...40000 (interrupts per second)
+Default:      2000
+
+This parameter is only used if either static or dynamic interrupt moderation
+is used on a network adapter card. Using this parameter if no moderation is
+applied will lead to no action performed.
+
+This parameter determines the length of any interrupt moderation interval. 
+Assuming that static interrupt moderation is to be used, an 'IntsPerSec' 
+parameter value of 2000 will lead to an interrupt moderation interval of
+500 microseconds. 
+
+NOTE: The duration of the moderation interval is to be chosen with care.
+At first glance, selecting a very long duration (e.g. only 100 interrupts per 
+second) seems to be meaningful, but the increase of packet-processing delay 
+is tremendous. On the other hand, selecting a very short moderation time might
+compensate the use of any moderation being applied.
+
+
+Preferred Port
+--------------
+Parameter:    PrefPort
+Values:       A, B
+Default:      A
+
+This is used to force the preferred port to A or B (on dual-port network 
+adapters). The preferred port is the one that is used if both are detected
+as fully functional.
+
+RLMT Mode (Redundant Link Management Technology)
+------------------------------------------------
+Parameter:    RlmtMode
+Values:       CheckLinkState,CheckLocalPort, CheckSeg, DualNet
+Default:      CheckLinkState
+
+RLMT monitors the status of the port. If the link of the active port 
+fails, RLMT switches immediately to the standby link. The virtual link is 
+maintained as long as at least one 'physical' link is up. 
+
+Possible modes:
+
+   -- CheckLinkState - Check link state only: RLMT uses the link state
+      reported by the adapter hardware for each individual port to 
+      determine whether a port can be used for all network traffic or 
+      not.
+
+   -- CheckLocalPort - In this mode, RLMT monitors the network path 
+      between the two ports of an adapter by regularly exchanging packets
+      between them. This mode requires a network configuration in which 
+      the two ports are able to "see" each other (i.e. there must not be 
+      any router between the ports).
+
+   -- CheckSeg - Check local port and segmentation: This mode supports the
+      same functions as the CheckLocalPort mode and additionally checks 
+      network segmentation between the ports. Therefore, this mode is only
+      to be used if Gigabit Ethernet switches are installed on the network
+      that have been configured to use the Spanning Tree protocol. 
+
+   -- DualNet - In this mode, ports A and B are used as separate devices. 
+      If you have a dual port adapter, port A will be configured as eth0 
+      and port B as eth1. Both ports can be used independently with 
+      distinct IP addresses. The preferred port setting is not used. 
+      RLMT is turned off.
+   
+NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations 
+      where a network path between the ports on one adapter exists. 
+      Moreover, they are not designed to work where adapters are connected
+      back-to-back.
+***
+
+
+5  Large Frame Support
+======================
+
+The driver supports large frames (also called jumbo frames). Using large 
+frames can result in an improved throughput if transferring large amounts 
+of data.
+To enable large frames, set the MTU (maximum transfer unit) of the 
+interface to the desired value (up to 9000), execute the following 
+command:
+      ifconfig eth0 mtu 9000
+This will only work if you have two adapters connected back-to-back
+or if you use a switch that supports large frames. When using a switch, 
+it should be configured to allow large frames and auto-negotiation should  
+be set to OFF. The setting must be configured on all adapters that can be 
+reached by the large frames. If one adapter is not set to receive large 
+frames, it will simply drop them.
+
+You can switch back to the standard ethernet frame size by executing the 
+following command:
+      ifconfig eth0 mtu 1500
+
+To permanently configure this setting, add a script with the 'ifconfig' 
+line to the system startup sequence (named something like "S99sk98lin" 
+in /etc/rc.d/rc2.d).
+***
+
+
+6  VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad)
+==================================================================
+
+The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and 
+Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad. 
+These features are only available after installation of open source 
+modules available on the Internet:
+For VLAN go to: http://www.candelatech.com/~greear/vlan.html
+For Link Aggregation go to: http://www.st.rim.or.jp/~yumo
+
+NOTE: SysKonnect GmbH does not offer any support for these open source 
+      modules and does not take the responsibility for any kind of 
+      failures or problems arising in connection with these modules.
+
+NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may 
+      cause problems when unloading the driver.
+
+
+7  Troubleshooting
+==================
+
+If any problems occur during the installation process, check the 
+following list:
+
+
+Problem:  The SK-98xx adapter cannot be found by the driver.
+Solution: In /proc/pci search for the following entry:
+             'Ethernet controller: SysKonnect SK-98xx ...'
+          If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has 
+          been found by the system and should be operational.
+          If this entry does not exist or if the file '/proc/pci' is not 
+          found, there may be a hardware problem or the PCI support may 
+          not be enabled in your kernel.
+          The adapter can be checked using the diagnostics program which 
+          is available on the SysKonnect web site:
+          www.syskonnect.com
+          
+          Some COMPAQ machines have problems dealing with PCI under Linux.
+          This problem is described in the 'PCI howto' document
+          (included in some distributions or available from the
+          web, e.g. at 'www.linux.org'). 
+
+
+Problem:  Programs such as 'ifconfig' or 'route' cannot be found or the 
+          error message 'Operation not permitted' is displayed.
+Reason:   You are not logged in as user 'root'.
+Solution: Logout and login as 'root' or change to 'root' via 'su'.
+
+
+Problem:  Upon use of the command 'ping <address>' the message
+          "ping: sendto: Network is unreachable" is displayed.
+Reason:   Your route is not set correctly.
+Solution: If you are using RedHat, you probably forgot to set up the 
+          route in the 'network configuration'.
+          Check the existing routes with the 'route' command and check 
+          if an entry for 'eth0' exists, and if so, if it is set correctly.
+
+
+Problem:  The driver can be started, the adapter is connected to the 
+          network, but you cannot receive or transmit any packets; 
+          e.g. 'ping' does not work.
+Reason:   There is an incorrect route in your routing table.
+Solution: Check the routing table with the command 'route' and read the 
+          manual help pages dealing with routes (enter 'man route').
+
+NOTE: Although the 2.2.x kernel versions generate the routing entry 
+      automatically, problems of this kind may occur here as well. We've 
+      come across a situation in which the driver started correctly at 
+      system start, but after the driver has been removed and reloaded,
+      the route of the adapter's network pointed to the 'dummy0'device 
+      and had to be corrected manually.
+
+
+Problem:  Your computer should act as a router between multiple 
+          IP subnetworks (using multiple adapters), but computers in 
+          other subnetworks cannot be reached.
+Reason:   Either the router's kernel is not configured for IP forwarding 
+          or the routing table and gateway configuration of at least one 
+          computer is not working.
+
+Problem:  Upon driver start, the following error message is displayed:
+          "eth0: -- ERROR --
+          Class: internal Software error
+          Nr:    0xcc
+          Msg:   SkGeInitPort() cannot init running ports"
+Reason:   You are using a driver compiled for single processor machines 
+          on a multiprocessor machine with SMP (Symmetric MultiProcessor) 
+          kernel.
+Solution: Configure your kernel appropriately and recompile the kernel or
+          the modules.

+The above events are not propagated by the driver, except for legacy

+
+Compatibility notes:
+
+ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
+supported the input layer, and sent events over the procfs ACPI event
+interface.
+
+To avoid sending duplicate events over the input layer and the ACPI
+event interface, thinkpad-acpi 0.16 implements a module parameter
+(hotkey_report_mode), and also a sysfs device attribute with the same
+name.
+
+Make no mistake here: userspace is expected to switch to using the input
+layer interface of thinkpad-acpi, together with the ACPI netlink event
+interface in kernels 2.6.23 and later, or with the ACPI procfs event
+interface in kernels 2.6.22 and earlier.
+
+If no hotkey_report_mode module parameter is specified (or it is set to
+zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
+and earlier, also allows one to change the hotkey_report_mode through
+sysfs.  In kernels 2.6.23 and later, where the netlink ACPI event
+interface is available, hotkey_report_mode cannot be changed through
+sysfs (it is read-only).
+
+If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
+be changed later through sysfs (any writes will return -EPERM to signal
+that hotkey_report_mode was locked.  On 2.6.23 and later, where
+hotkey_report_mode cannot be changed at all, writes will return -EACES).
+
+hotkey_report_mode set to 1 makes the driver export through the procfs
+ACPI event interface all hot key presses (which are *also* sent to the
+input layer).  This is a legacy compatibility behaviour, and it is also
+the default mode of operation for the driver.
+
+hotkey_report_mode set to 2 makes the driver filter out the hot key
+presses from the procfs ACPI event interface, so these events will only
+be sent through the input layer.  Userspace that has been updated to use
+the thinkpad-acpi input layer interface should set hotkey_report_mode to
+2.
+
+Hot key press events are never sent to the ACPI netlink event interface.
+Really up-to-date userspace under kernel 2.6.23 and later is to use the
+netlink interface and the input layer interface, and don't bother at all
+with hotkey_report_mode.
