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@...konnect.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 -*** - - - -***End of Readme File*** -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
