+===========================
+0. Introduction
+------------ -----   -----       ----       ---       --         -     
+
+This document provides a brief overview of the features supported by the 
+IPW2100 driver project.  The main project website, where the latest 
+development version of the driver can be found, is:
+
+       http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+===========================
+1. Release 1.1.0 Current Supported Features
+---------------------------     
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support 
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+===========================
+2. Command Line Parameters
+---------------------------     
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax:
+
+       modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+       modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+Name           Value           Example:
+debug          0x0-0xffffffff  debug=1024
+mode           0,1,2           mode=1   /* AdHoc */
+channel                int             channel=3 /* Only valid in AdHoc or Monitor */
+associate      boolean         associate=0 /* Do NOT auto associate */
+disable                boolean         disable=1 /* Do not power the HW */
+
+
+===========================
+3. Sysfs Helper Files
+---------------------------     
+
+There are several ways to control the behavior of the driver.  Many of the 
+general capabilities are exposed through the Wireless Tools (iwconfig).  There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+  debug_level  
+       
+       This controls the same global as the 'debug' module parameter.  For 
+        information on the various debugging levels available, run the 'dvals'
+       script found in the driver source directory.
+
+       NOTE:  'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+              on.
+
+----- Device Level ------
+For the device level files look in
+       
+       /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example:
+       /sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+  rf_kill
+       read - 
+       0 = RF kill not enabled (radio on)
+       1 = SW based RF kill active (radio off)
+       2 = HW based RF kill active (radio off)
+       3 = Both HW and SW RF kill active (radio off)
+       write -
+       0 = If SW based RF kill active, turn the radio back on
+       1 = If radio is on, activate SW based RF kill
+
+       NOTE: If you enable the SW based RF kill and then toggle the HW
+       based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+===========================
+4. Radio Kill Switch
+---------------------------
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on.  On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on.  This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+===========================
+5. Dynamic Firmware
+---------------------------     
+As the firmware is licensed under a restricted use license, it can not be 
+included within the kernel sources.  To enable the IPW2100 you will need a 
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+===========================
+6. Power Management
+---------------------------     
+The IPW2100 supports the configuration of the Power Save Protocol 
+through a private wireless extension interface.  The IPW2100 supports 
+the following different modes:
+
+       off     No power management.  Radio is always on.
+       on      Automatic power management
+       1-5     Different levels of power management.  The higher the 
+               number the greater the power savings, but with an impact to 
+               packet latencies. 
+
+Power management works by powering down the radio after a certain 
+interval of time has passed where no packets are passed through the 
+radio.  Once powered down, the radio remains in that state for a given 
+period of time.  For higher power savings, the interval between last 
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station 
+must buffer packets at the AP until the station wakes up and requests 
+any buffered packets.  If you have an AP that does not correctly support 
+the PSP protocol you may experience packet loss or very poor performance 
+while power management is enabled.  If this is the case, you will need 
+to try and find a firmware update for your AP, or disable power 
+management (via `iwconfig eth1 power off`)
+
+To configure the power level on the IPW2100 you use a combination of 
+iwconfig and iwpriv.  iwconfig is used to turn power management on, off, 
+and set it to auto.
+
+       iwconfig eth1 power off    Disables radio power down
+       iwconfig eth1 power on     Enables radio power management to 
+                                  last set level (defaults to AUTO)
+       iwpriv eth1 set_power 0    Sets power level to AUTO and enables 
+                                  power management if not previously 
+                                  enabled.
+       iwpriv eth1 set_power 1-5  Set the power level as specified, 
+                                  enabling power management if not 
+                                  previously enabled.
+
+You can view the current power level setting via:
+       
+       iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to 
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'.  If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.

+1.   Introduction
+-----------------------------------------------
+The following sections attempt to provide a brief introduction to using 
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on 
+understanding or using wireless technologies, but should be sufficient 
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-----------------------------------------------
+The current release (1.0.0) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support 
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless 
+2915ABG Driver for Linux allows certain configuration options to be 
+provided as module parameters.  The most common way to specify a module 
+parameter is via the command line.  
+
+The general form is:
+
+% modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+  associate
+       Set to 0 to disable the auto scan-and-associate functionality of the
+       driver.  If disabled, the driver will not attempt to scan 
+       for and associate to a network until it has been configured with 
+       one or more properties for the target network, for example configuring 
+       the network SSID.  Default is 1 (auto-associate)
+       
+       Example: % modprobe ipw2200 associate=0
+
+  auto_create
+       Set to 0 to disable the auto creation of an Ad-Hoc network 
+       matching the channel and network name parameters provided.  
+       Default is 1.
+
+  channel
+       channel number for association.  The normal method for setting
+        the channel would be to use the standard wireless tools
+        (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+       to set this while debugging.  Channel 0 means 'ANY'
+
+  debug
+       If using a debug build, this is used to control the amount of debug
+       info is logged.  See the 'dval' and 'load' script for more info on
+       how to use this (the dval and load scripts are provided as part 
+       of the ipw2200 development snapshot releases available from the 
+       SourceForge project at http://ipw2200.sf.net)
+
+  mode
+       Can be used to set the default mode of the adapter.  
+       0 = Managed, 1 = Ad-Hoc
+
+
+1.3. Wireless Extension Private Methods
+-----------------------------------------------
+
+As an interface designed to handle generic hardware, there are certain 
+capabilities not exposed through the normal Wireless Tool interface.  As 
+such, a provision is provided for a driver to declare custom, or 
+private, methods.  The Intel(R) PRO/Wireless 2915ABG Driver for Linux 
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is:
+
+       % iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with 
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+  get_mode
+       Can be used to report out which IEEE mode the driver is 
+       configured to support.  Example:
+       
+       % iwpriv eth1 get_mode
+       eth1    get_mode:802.11bg (6)
+
+  set_mode
+       Can be used to configure which IEEE mode the driver will 
+       support.  
+
+       Usage:
+       % iwpriv eth1 set_mode {mode}
+       Where {mode} is a number in the range 1-7:
+       1       802.11a (2915 only)
+       2       802.11b
+       3       802.11ab (2915 only)
+       4       802.11g 
+       5       802.11ag (2915 only)
+       6       802.11bg
+       7       802.11abg (2915 only)
+
+  get_preamble
+       Can be used to report configuration of preamble length.
+
+  set_preamble
+       Can be used to set the configuration of preamble length:
+
+       Usage:
+       % iwpriv eth1 set_preamble {mode}
+       Where {mode} is one of:
+       1       Long preamble only
+       0       Auto (long or short based on connection)
+       
+
+1.4. Sysfs Helper Files:
+-----------------------------------------------
+
+The Linux kernel provides a pseudo file system that can be used to 
+access various components of the operating system.  The Intel(R) 
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration 
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing.  You can 
+typically query the contents of a sysfs entry through the use of cat, 
+and can set the contents via echo.  For example:
+
+% cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem 
+(only available if CONFIG_IPW_DEBUG was configured when the driver was 
+built).
+
+You can set the debug level via:
+
+% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry.  The 
+input to sysfs files does not have to be a number.  For example, the 
+firmware loader used by hotplug utilizes sysfs entries for transferring 
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries 
+at two levels -- driver level, which apply to all instances of the 
+driver (in the event that there are more than one device installed) and 
+device level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+-----------------------------------------------
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+  debug_level  
+       
+       This controls the same global as the 'debug' module parameter
+
+
+1.4.2 Device Level Sysfs Helper Files
+-----------------------------------------------
+
+For the device level files, look in
+       
+       /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:
+       /sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/[drivers/ipw2200:
+
+  rf_kill
+       read - 
+       0 = RF kill not enabled (radio on)
+       1 = SW based RF kill active (radio off)
+       2 = HW based RF kill active (radio off)
+       3 = Both HW and SW RF kill active (radio off)
+       write -
+       0 = If SW based RF kill active, turn the radio back on
+       1 = If radio is on, activate SW based RF kill
+
+       NOTE: If you enable the SW based RF kill and then toggle the HW
+       based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+       
+  ucode 
+       read-only access to the ucode version number
+
+
+2.   About the Version Numbers
+-----------------------------------------------
+
+Due to the nature of open source development projects, there are 
+frequently changes being incorporated that have not gone through 
+a complete validation process.  These changes are incorporated into 
+development snapshot releases.
+
+Releases are numbered with a three level scheme: 
+
+       major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made 
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users.  The stability 
+and functionality of the development releases are not know.  We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases 
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver.  Currently, there are no major changes planned.
+
+
+3.  Support

+
+INTRODUCTION
+============
+
+ This document describes the Linux driver for Chelsio 10Gb Ethernet Network
+ Controller. This driver supports the Chelsio N210 NIC and is backward
+ compatible with the Chelsio N110 model 10Gb NICs.
+
+
+FEATURES
+========
+
+ Adaptive Interrupts (adaptive-rx)
+ ---------------------------------
+
+  This feature provides an adaptive algorithm that adjusts the interrupt
+  coalescing parameters, allowing the driver to dynamically adapt the latency
+  settings to achieve the highest performance during various types of network
+  load.
+
+  The interface used to control this feature is ethtool. Please see the
+  ethtool manpage for additional usage information.
+
+  By default, adaptive-rx is disabled.
+  To enable adaptive-rx:
+
+      ethtool -C <interface> adaptive-rx on
+
+  To disable adaptive-rx, use ethtool:
+
+      ethtool -C <interface> adaptive-rx off
+
+  After disabling adaptive-rx, the timer latency value will be set to 50us.
+  You may set the timer latency after disabling adaptive-rx:
+
+      ethtool -C <interface> rx-usecs <microseconds>
+
+  An example to set the timer latency value to 100us on eth0:
+
+      ethtool -C eth0 rx-usecs 100
+
+  You may also provide a timer latency value while disabling adpative-rx:
+
+      ethtool -C <interface> adaptive-rx off rx-usecs <microseconds>
+
+  If adaptive-rx is disabled and a timer latency value is specified, the timer
+  will be set to the specified value until changed by the user or until
+  adaptive-rx is enabled.
+
+  To view the status of the adaptive-rx and timer latency values:
+
+      ethtool -c <interface>
+
+
+ TCP Segmentation Offloading (TSO) Support
+ -----------------------------------------
+
+  This feature, also known as "large send", enables a system's protocol stack
+  to offload portions of outbound TCP processing to a network interface card
+  thereby reducing system CPU utilization and enhancing performance.
+
+  The interface used to control this feature is ethtool version 1.8 or higher.
+  Please see the ethtool manpage for additional usage information.
+
+  By default, TSO is enabled.
+  To disable TSO:
+
+      ethtool -K <interface> tso off
+
+  To enable TSO:
+
+      ethtool -K <interface> tso on
+
+  To view the status of TSO:
+
+      ethtool -k <interface>
+
+
+PERFORMANCE
+===========
+
+ The following information is provided as an example of how to change system
+ parameters for "performance tuning" an what value to use. You may or may not
+ want to change these system parameters, depending on your server/workstation
+ application. Doing so is not warranted in any way by Chelsio Communications,
+ and is done at "YOUR OWN RISK". Chelsio will not be held responsible for loss
+ of data or damage to equipment.
+
+ Your distribution may have a different way of doing things, or you may prefer
+ a different method. These commands are shown only to provide an example of
+ what to do and are by no means definitive.
+
+ Making any of the following system changes will only last until you reboot
+ your system. You may want to write a script that runs at boot-up which
+ includes the optimal settings for your system.
+
+  Setting PCI Latency Timer:
+      setpci -d 1425:* 0x0c.l=0x0000F800
+
+  Disabling TCP timestamp:
+      sysctl -w net.ipv4.tcp_timestamps=0
+
+  Disabling SACK:
+      sysctl -w net.ipv4.tcp_sack=0
+
+  Setting large number of incoming connection requests:
+      sysctl -w net.ipv4.tcp_max_syn_backlog=3000
+
+  Setting maximum receive socket buffer size:
+      sysctl -w net.core.rmem_max=1024000
+
+  Setting maximum send socket buffer size:
+      sysctl -w net.core.wmem_max=1024000
+
+  Set smp_affinity (on a multiprocessor system) to a single CPU:
+      echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+  Setting default receive socket buffer size:
+      sysctl -w net.core.rmem_default=524287
+
+  Setting default send socket buffer size:
+      sysctl -w net.core.wmem_default=524287
+
+  Setting maximum option memory buffers:
+      sysctl -w net.core.optmem_max=524287
+
+  Setting maximum backlog (# of unprocessed packets before kernel drops):
+      sysctl -w net.core.netdev_max_backlog=300000

+      sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
+
+  Setting TCP write buffers (min/pressure/max):
+      sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
+
+  Setting TCP buffer space (min/pressure/max):
+      sysctl -w net.ipv4.tcp_mem="10000000 10000000 10000000"
+
+  TCP window size for single connections:
+   The receive buffer (RX_WINDOW) size must be at least as large as the
+   Bandwidth-Delay Product of the communication link between the sender and
+   receiver. Due to the variations of RTT, you may want to increase the buffer
+   size up to 2 times the Bandwidth-Delay Product. Reference page 289 of
+   "TCP/IP Illustrated, Volume 1, The Protocols" by W. Richard Stevens.
+   At 10Gb speeds, use the following formula:
+       RX_WINDOW >= 1.25MBytes * RTT(in milliseconds)
+       Example for RTT with 100us: RX_WINDOW = (1,250,000 * 0.1) = 125,000
+   RX_WINDOW sizes of 256KB - 512KB should be sufficient.
+   Setting the min, max, and default receive buffer (RX_WINDOW) size:
+       sysctl -w net.ipv4.tcp_rmem="<min> <default> <max>"
+
+  TCP window size for multiple connections:
+   The receive buffer (RX_WINDOW) size may be calculated the same as single
+   connections, but should be divided by the number of connections. The
+   smaller window prevents congestion and facilitates better pacing,
+   especially if/when MAC level flow control does not work well or when it is
+   not supported on the machine. Experimentation may be necessary to attain
+   the correct value. This method is provided as a starting point fot the
+   correct receive buffer size.
+   Setting the min, max, and default receive buffer (RX_WINDOW) size is
+   performed in the same manner as single connection.
+
+

+
+
+KNOWN ISSUES
+============
+
+ These issues have been identified during testing. The following information
+ is provided as a workaround to the problem. In some cases, this problem is
+ inherent to Linux or to a particular Linux Distribution and/or hardware
+ platform.
+
+  1. Large number of TCP retransmits on a multiprocessor (SMP) system.
+
+      On a system with multiple CPUs, the interrupt (IRQ) for the network
+      controller may be bound to more than one CPU. This will cause TCP
+      retransmits if the packet data were to be split across different CPUs
+      and re-assembled in a different order than expected.
+
+      To eliminate the TCP retransmits, set smp_affinity on the particular
+      interrupt to a single CPU. You can locate the interrupt (IRQ) used on
+      the N110/N210 by using ifconfig:
+          ifconfig <dev_name> | grep Interrupt
+      Set the smp_affinity to a single CPU:
+          echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+      It is highly suggested that you do not run the irqbalance daemon on your
+      system, as this will change any smp_affinity setting you have applied.
+      The irqbalance daemon runs on a 10 second interval and binds interrupts
+      to the least loaded CPU determined by the daemon. To disable this daemon:
+          chkconfig --level 2345 irqbalance off
+
+      By default, some Linux distributions enable the kernel feature,
+      irqbalance, which performs the same function as the daemon. To disable
+      this feature, add the following line to your bootloader:
+          noirqbalance
+
+          Example using the Grub bootloader:
+              title Red Hat Enterprise Linux AS (2.4.21-27.ELsmp)
+              root (hd0,0)
+              kernel /vmlinuz-2.4.21-27.ELsmp ro root=/dev/hda3 noirqbalance
+              initrd /initrd-2.4.21-27.ELsmp.img
+
+  2. After running insmod, the driver is loaded and the incorrect network
+     interface is brought up without running ifup.
+
+      When using 2.4.x kernels, including RHEL kernels, the Linux kernel
+      invokes a script named "hotplug". This script is primarily used to
+      automatically bring up USB devices when they are plugged in, however,
+      the script also attempts to automatically bring up a network interface
+      after loading the kernel module. The hotplug script does this by scanning
+      the ifcfg-eth# config files in /etc/sysconfig/network-scripts, looking
+      for HWADDR=<mac_address>.
+
+      If the hotplug script does not find the HWADDRR within any of the
+      ifcfg-eth# files, it will bring up the device with the next available
+      interface name. If this interface is already configured for a different
+      network card, your new interface will have incorrect IP address and
+      network settings.
+
+      To solve this issue, you can add the HWADDR=<mac_address> key to the
+      interface config file of your network controller.
+
+      To disable this "hotplug" feature, you may add the driver (module name)
+      to the "blacklist" file located in /etc/hotplug. It has been noted that
+      this does not work for network devices because the net.agent script
+      does not use the blacklist file. Simply remove, or rename, the net.agent
+      script located in /etc/hotplug to disable this feature.
+
+  3. Transport Protocol (TP) hangs when running heavy multi-connection traffic
+     on an AMD Opteron system with HyperTransport PCI-X Tunnel chipset.
+
+      If your AMD Opteron system uses the AMD-8131 HyperTransport PCI-X Tunnel
+      chipset, you may experience the "133-Mhz Mode Split Completion Data
+      Corruption" bug identified by AMD while using a 133Mhz PCI-X card on the
+      bus PCI-X bus.
+
+      AMD states, "Under highly specific conditions, the AMD-8131 PCI-X Tunnel
+      can provide stale data via split completion cycles to a PCI-X card that
+      is operating at 133 Mhz", causing data corruption.
+
+      AMD's provides three workarounds for this problem, however, Chelsio
+      recommends the first option for best performance with this bug:
+
+        For 133Mhz secondary bus operation, limit the transaction length and
+        the number of outstanding transactions, via BIOS configuration
+        programming of the PCI-X card, to the following:
+
+           Data Length (bytes): 1k
+           Total allowed outstanding transactions: 2
+
+      Please refer to AMD 8131-HT/PCI-X Errata 26310 Rev 3.08 August 2004,
+      section 56, "133-MHz Mode Split Completion Data Corruption" for more
+      details with this bug and workarounds suggested by AMD.
+
+      It may be possible to work outside AMD's recommended PCI-X settings, try
+      increasing the Data Length to 2k bytes for increased performance. If you
+      have issues with these settings, please revert to the "safe" settings
+      and duplicate the problem before submitting a bug or asking for support.
+
+      NOTE: The default setting on most systems is 8 outstanding transactions
+            and 2k bytes data length.
+
+  4. On multiprocessor systems, it has been noted that an application which
+     is handling 10Gb networking can switch between CPUs causing degraded
+     and/or unstable performance.
+
+      If running on an SMP system and taking performance measurements, it
+      is suggested you either run the latest netperf-2.4.0+ or use a binding
+      tool such as Tim Hockin's procstate utilities (runon)
+      <http://www.hockin.org/~thockin/procstate/>.
+
+      Binding netserver and netperf (or other applications) to particular
+      CPUs will have a significant difference in performance measurements.
+      You may need to experiment which CPU to bind the application to in
+      order to achieve the best performance for your system.
+
+      If you are developing an application designed for 10Gb networking,
+      please keep in mind you may want to look at kernel functions
+      sched_setaffinity & sched_getaffinity to bind your application.
+
+      If you are just running user-space applications such as ftp, telnet,
+      etc., you may want to try the runon tool provided by Tim Hockin's
+      procstate utility. You could also try binding the interface to a
+      particular CPU: runon 0 ifup eth0
