+===========================================================================
+
+
+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.
+
+
+
+If your problem is not listed here, please contact SysKonnect's technical
+support for help (linux@syskonnect.de).
+When contacting our technical support, please ensure that the following
+information is available:
+- System Manufacturer and HW Informations (CPU, Memory... )
+- PCI-Boards in your system
+- Distribution
+- Kernel version
+- Driver version

+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.
